Probability Distribution for the Random Variable X

1)34% of people in the US have type A-positive blood. Five people are randomly selected and asked if their blood type is A-positive. Construct a probability distribution for the random variable x. Find the probabilities P(0), p(1), P(2), P(3),
P(4), and P(5). Round to the nearest thousandth.

2) 95% of people in the US have tupe B-positive blood. Five people are randomly selected and asked if their blood type is B-positive. use the given probability distribution to find the mean, variance and the st/dv of the distribution.

a) mean= round to the nearest hundredth
b) variance= round to four decimal places.
c) st/dv= round to four decimal places.
