Event a has a 0.3 probability of occurring and event b has a 0.4 probability of occurring. a and b are independent events. what is the probability that neither a or b occurs? a. 0.42 b. 0.12 c. 0.10 d. 0.70

The correct answer is A.  0.42

Step-by-step explanation:

Probability that neither A nor B occurs  

Hence, the required probability is 0.42 and the correct option is A

1. 8

2. 9

3. 20

4. 3

5. 17

6. 2.2

7. 11.25

8. 1

9. 14

10. 2

step-by-step explanation:

thats the first half

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional
