Answer 9

X=2 means the trials right?

Answer 10

Answer 11

yeah thats what threw me off aswell

Answer 12

it is not D do you know why

Answer 13

i've always hated probabilities lol

Answer 14

lmao im barely starting it and i can tell why

Answer 15

if the possibility of succeeding is .8 does that mean that fail is .2 right

Answer 16

so so the chance to succeed for d is .64 or 64%

Answer 17

which mean that the chance to fail twice is 0.04 or 4%

Answer 18

you're making sense really but D can't be the answer they gave a high expected percentage

Answer 19

so 32% for 1 fail and one succeed right

Answer 20

maybe im approaching it wrong then
