a coin is loaded so that the probabilityof getting heads 3/4. if the coin is flipped twice,what is the probability of gettiing heads twiice
2/4 i think
This is the same kind of problem as your other one. The probability of getting heads the first time is?
1/2
No, the question specifically says that the coin is loaded so it's 3/4
o
And on the second flip you still have another 3/4 chance of getting heads.
6/8
So the probability of getting both is the probability of the first, times the probability of the second.
9/16
Correct. Anytime you have 2 different events that both must occur you have to multiply the probability for each event together.
Same thing for the letters/numbers problem you were asking about before. It would be 3/6 chance of a number being even 1/3 chance of a letter being a So probability of both would be 3/6 times 1/3 = 3/18 = 1/6
