Find the area under the standard normal curve to the left of z = -1.33.

Question 2

If A and B are independent events, and P(A) = 0.7 and P(B) = 0.6, find P(A and B)

[AmberC1996]

Answer to Question 1

P(z<-1.33) = 0.50  0.4082 = 0.0918

Answer to Question 2

P(A and B) = P(A) P(B) = (0.7)(0.6) = 0.42
