How to solve (b) ?

It is generally considered bad form to post the same question to multiple forums.
You were doing so well with a) and b), what stopped you on c)? Just not understanding the question?

You could try bin(5,0.4)?

I’m sorry? What do you mean by multiple forums? Sorry this is my first time using this forum. There are only two questions (a) and (b), don’t have (c) . I don’t understand (b)

I see. I took the identification of the appropriate binomial distribution as part a), making the other two a little farther down the alphabet.

Maybe this is a classmate - studying the same material?

Probability

Experience shows that 40% of the throws of a bowler result in strikes. Find the probability that at most five throws need to be made by the bowler so that four throws result in strikes.
