57% of men consider themselves professional baseball fans. you randomly select 10 men and ask each if he considers himself a professional baseball fan. find the probability that the number who consider themselves baseball fans is (a) exactly five, (b) at least six, and (c) less than four.

 A

Step-by-step explanation:

Use this equation:

57/100 = X/10.

Cross multiply the two fractions (57x10)

=570

Now divide 570 by the only number left, 100.

=5.7

To solve this question, you have to estimate a little bit and find the closest answer.

x = ± 6i

step-by-step explanation:

x^2 = -36

take the square root of each side

sqrt(x^2) = sqrt(-36)

we know sqrt(ab) = sqrt(a) sqrt(b)

x = ±sqrt(36) sqrt(-1)

we know that sqrt (-1) = i

x = ± 6i
