Sorry but i have a few different questions.

1. The events A and B are mutually exclusive. If ()=0.2 and ()=0.6, what is ( )?

2.Mamma Temte bakes six pies a day that cost $2 each to produce. On 15% of the days she sells only two pies. On 30% of the days, she sells 4 pies, and on the remaining 55% of the days, she sells all six pies. If Mama Temte sells her pies for $6 each, what is her expected profit for a day's worth of pies? [Assume that any leftover pies are given away.] 3. We believe that 86% of the population of all Calculus I students consider calculus an exciting subject. Suppose we randomly and independently selected 29 students from the population. If the true percentage is really 86%, find the probability of observing 28 or more of the students who consider calculus to be an exciting subject in our sample of 29. 4. A recent survey found that 69% of all adults over 50 wear sunglasses for driving. In a random sample of 20 adults over 50, what is the mean and standard deviation of those that wear sunglasses?

if you could help me figure these out I would be so grateful! Thank you!
