Answer 2

#2 is a math question? o.O

Answer 3

@dude #2 is asking us which events are dependent?

Answer 4

(#10 is asking us which events are independent)

Answer 5

@dude @Vocaloid

Answer 6

"at least one year" includes 1 year, 2 years, and 3 years

Answer 7

i mean, I guess they might just want the 1-year column only, but the way they've worded it it would technically include everyone

Answer 8

so, my answer for #5 is not correct?

Answer 9

0.71 probably is what they're looking for, just not well worded

Answer 10

what about the rest of them?

Answer 11

would 0.70 be better rounded for #5?

Answer 12

since I rounded 0.706

Answer 13

0.71 is better

for 8 it's not P(A) + P(B), it's P(A and B)

"at the same time" implies "A and B"

Answer 14

I think the other ones are fine
