Could someone please help me on this conditional probablity problem?
A balanced dime is tossed twice. The four possible equaly likely outcomes are HH,HT, TH, TT
A=event the first toss is heads
B=event the second toss is heads
C=event at least one toss is heads
Determine the following probabilities and express your results in words. Compute the conditional probabilities directly; do not use the conditional probability rule
Would it be 3/4???????
Would it be 1/3????????
Would this also be 1/3???????
f. P(|not B))
I really don't understand this. Could someone please explain this to me so that I can do the rest that are like this?
any help would be greatly appreciated
Thank you very much
