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

where are the choices?

a reflection across the x-axis , followed by the by a reflection across the y-axis , and then a scale dilation of 0.5 .
