Question

Greg has a 20% chance of being selected as the president of the school sports club and a 90% chance of being elected editor of the school magazine.

What is the probability that Greg will be selected as the president of the sports club and will also be elected editor of the school magazine?
11%
18%
45%
70%

Answer 1

multiply the two probabilities together

Answer 2

I'm relying on the division factor here. If it's 20 into 90 then it'll come to 45% which is one of your answer choices, but I could be wrong. o.o

Answer 3

What do you think the answer is, @Tinky711 ? :)

Answer 4

this is a compound event

the probability of one event is 0.20
the probability of the second event is 0.90

so the probability of both events happening is 0.2*0.9 = ?

Answer 5

So 0.18 would be the answer right?

Answer 6

0.18 was my first answer but I wanted to make sure i was right. @Cresciez
