P(x=5)+p(x=6)
where you have a binomial rv with n=6 and p=.55
show me your work and I'll examine it.
(2) is 4 (.62)^3(.38) which is approximately .36225856
There are 2 questions:
A basketball player makes free throws with a 0.55 probability. What is the probability that the player will make at least 5 of the next 6 free throws?
The answer I got for this was 0.1359 if you round via 4 decimals. But checker says this is wrong. I've double checked my work and I don't think it's wrong.
The other question was:
An unfair coin with 0.62 probability of tails is flipped 4 times. What is the probability of obtaining exactly 3 heads?
The answer I got for this was 0.3623 if you round via 4 decimals. Again the same problem with it.
Is this correct or did I just get the wrong answer entirely?
AHA I think I got what you meant there. I'll do some quick reworking.
.163571 for the basketball problem.
Ok, so now that I have that out of the way....is the 2nd answer correct?
edit: I was going to hit the thanks button ;p you didn't have to hint!
And I figured out what was wrong with the 2nd answer....we're both wrong cause we didn't have the correct probability!
