So we are given the probabilities of q and r:

p (q) = 0.12

p (r) = 0.25

p (q and r) = 0.03

 

Actually to find for p (q or r), this simply means to add all the values of p (q). p (r) and p (q and r). If we are to draw a bubble diagram, the p (q and r) is the bubble intersection p (q) and p (r). We know that the word “OR” takes up all in the bubble diagram. Therefore:

p (q or r) = p (q) + p (r) + p (q and r)

 

Substituting the given values into the equation:

p (q or r) = 0.12 + 0.25 + 0.03

<span>p (q or r) = 0.40</span>

Answer:

0.34

Step-by-step explanation:

The probability of A or B occurring if they are not mutually exclusive is given by

P(A)+P(B)-P(A and B)

In this case, we have

P(q)+P(r)-P(q and r)

= 0.12+0.25-0.03 = 0.34

66

Step-by-step explanation:

Both bottom angles are equal

So x+x+48=180

Subtract 48 from both sides

So 2x=132

Divide both sides by 2

x=66
