: 1) The probability a basketball player makes a free throw is 0.60. Find the probability the player makes four out of 6.
2) In a binomial distribution, the probability of 25 successes, where n = 65 and p = 0.35 is
3) The probability that Andy studies math over break is 0.3 and the probability that Betty independently studies over break is 0.4. Find the probability Andy studies math over break and Betty doesn't.

You can put this solution on YOUR website! 1) The probability a basketball player makes a free throw is 0.60. Find the probability the player makes four out of 6.
P(4 of 6) = 6C4(0.6)^4(0.4)^2 = 0.31104..
------------------------------
2) In a binomial distribution, the probability of 25 successes, where n = 65 and p = 0.35 is .....65C25(0.35)^25(0.65)40 = 0.08556...
---------------------------------
3) The probability that Andy studies math over break is 0.3 and the probability that Betty independently studies over break is 0.4. Find the probability Andy studies math over break and Betty doesn't = 0.3*0.6 = 0.18.
=============================
4) The area under a normal curve between the scores for z = 2.20 and z = 0.85 is 0.183759...
You have to use your z-chart or your calculator to find this answer.
