Im not sure if you find the difference and take that as an answer which would be 50% or add it up and take 90%

OpenStudy (anonymous):

see i thought it was 90 but im not 100% sure but i have to b 100% sure because this grade is if i fail my class or if i pass

multiply the probabilities, since it is asking 'and'

OpenStudy (perl):

. What is the probability that it will rain tomorrow `and` the volleyball game will be postponed? .70 * .20

OpenStudy (perl):

i changed the percent to decimal, so it is easier to multiply
