Need help with a a homework question
Consider a finacial analysts predicting a 10 stocks for the week ahead. We have that the probability that one prediction is correct is .48.
What is the probability that this financial analyst predicts 6 stocks prices correctly?

Hello, and welcome to FMH!

How many ways can we choose 6 of the 10 stocks? For each such choice, what is the probability that 6 are correct, and 4 are incorrect? Notice that we are essentially talking about the binomial probability formula.

This a comment. I have no doubt that the problem means that we are to take the predictions as independent with probability $$\displaystyle 0.48$$.
However, I could see how a test taker could read "the probability that one prediction is correct is .48" as one in ten is correct.
It seems the question should be better put.
