Hi there! Have questions about your homework? At Brainly, there are 60 million students who want to help each other learn. Questions are usually answered in less than 10 minutes. Try it for yourself by posting a question! :D

Q.1.'A' speaks truth in 80% cases and 'B' in 70% cases.Find the probability that they contradict each other in a single event.

Q.2.A problem in Mathematics is given to 3 students A,b and C and their respective probabilities of solving the problem are 0.5, 0.33 and 0.25.Find the probability of the question being solved.

Solutions along with answers would be appreciated.

I figured out how to do it. The probability of question being solved will be 1-P(not being solved) therefore, ans is 1-(1/2)(2/3)(3/4)=1-6/24=3/4 (Since probability of A not solving it is 1-1/2=1/2, B not solving is 1-1/3=2/3 and C not solving is 1-1/4=3/4) You were way off.Thanks anyway though.
