Suppose q and r are independent events, and p(q) = 0.45, p(r) = 0.31. find p(q and r).
a. 0.1395
b. 0.063
c. 0.14
d. 0.76

0.1395

Step-by-step explanation:

We are given that Q and R are independent events.

P(Q)=0.45

P(R)=0.31

We have to find the value of P(Q and R).

We know that when two events are independent then

P( Q and R)=0.1395

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11
