Question

A die is rolled twice find the probability that 4 will come up exactly one time

Answer 1

probability = no.of outcome/no.of possible outcomes
2/12
therefore probability of 4 to come is 1/6.

Answer 2

Answer:

Step-by-step explanatNo.s ion:

Dice is thrown 2 times . We are asked to find how many times 4 will come if the dice is thrown twice .

Total No of observation( dice is having 6 chances) = 6×2 =12 times chances

Four can come 2 times therefore

No of observation =2

No of observation/ total no of observation=2/12=1/6
