Sir, I want to ask you a question of probability.

Two dice are thrown twice. Find the probability of getting an even number on the first die or a total of 8.

Tried a lot but not getting the right answer. Please if you could help me.

Thank you.

Hi Ruchi
Take E as a event of getting first even nos. And F as event of getting sum 8 ..
F=[ 26 62 44 53 35 ]
E=[ 3*6 ]
E intersect F = 3
P(F)= 18
P(E/F)=3/18=1/6

Sir, the p(f) value is supposed to be 5/36 right. but you wrote 4/36.. and then the final answer should be 20/36 instead of 19/36….

• 15/02/2015

Hi Ruchi,
Take E as a event of getting even no. on first throw & F as event of getting sum 8.
E = {(2,1), (2,2), …, (2,6), (4,1), …(4,6), (6,1), …, (6,6)}
F = {(2,6), (3,5), (4,4), (5,3) (6,2)}
So, n(E intersection F) = 3
P(E or F) = P(E) + P(F) – P(E intersection F) = 18/36 + 4/36 – 3/36 = 19/36
