I don't know much about cards so could someone help me?

If two cards are drawn from a standard deck of playing cards without replacement, find the probability that at least two are red?

I tried it out and I got 10/663 o,O isn't that way off? Could someone help me please!

Home >All Categories > Science & Mathematics >Mathematics >Open Question Musicalr... Member since:July 12, 2008Total points:2,753 (Level 4)Parents with the genotypes AaBbCc and AaBbCc are crossed, what is the probability that the offspring will have the genotype AaBbCc? I got 1/27 (3.7%) when I made a punnett square, but my prof wants us to calculate this like she did in class. I wasn't there for the class; what I can tell from the powerpoint is that she did this:
AaxAa=1/2 Aa
BbxBb=1/2 Bb
CcxCc=1/2 Cc
I'm not sure if she then calculated the probability like this:
(1/2)*(1/2)*(1/2)= 12.5%
Which method is correct? How would you calculate the probability by using fractions? I need to show my work, and there's no way that I can have a 27 square punnett square for each problem. Thanks!!Answer Question

THe 1/2 X 1/2 X 1/2 = 1/8 = 0.125 is correct

You are looking at each independently-assorting trait independently. Using the multiplication rule of probability, probability of 3 independent events occurring simultaneously is the product of their individual probabilities.

In your Punnet Square, you would have an 8X8 square with 64 boxes. 8 of those should have had AaBbCc in them, giving you a 1/8 probability.

While I haven't taken a statistics class, it seems like the answer would be 2 out of 36 (or 1 out of 18).

There are 36 possible outcomes when rolling two dice (for each of the 6 possibilities on die A, there are 6 possibilities on die B). Only two of these outcomes (6,5) and (5,6) add up to 11.

Cars are being produced by two factories, but factory I produces twice as many cars as factory II in a given time. Factory I is known to produce 1% defectives and factory II produces 3% defectives. A car is examined and found to be defective. What is the probability the car came from factory I if it is defective?

Please show all work I have no idea where to begin. Thank you.

regarding their 401(k) investments, the following data
were obtained:

60 had investments in money market funds.
47 had investments in stock funds and bond funds.
36 had investments in stock funds and money market
funds.
36 had investments in bond funds and money market
funds.
22 had investments in stock funds, bond funds, and
money market funds.

What is the probability that an employee of the company
chosen at random
a. Had investments in exactly two kinds of investment
funds?
b. Had investments in exactly one kind of investment
fund?
c. Had no investment in any of the three types of funds?
