1. ## [SOLVED] Bernoulli Trials

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?

2. 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

3. This is the first one:

If you got that for number 2, then that means that my answer of .3623 is SUPPOSED to be correct.

The proff told us to round to 4 decimals.

4. YOU found P(X=5) NOT at least 5 of the next 6

5. AHA I think I got what you meant there. I'll do some quick reworking.
