Since there are 6 sides and only one 4, the probability of rolling a 4 is one in 6 or 1/6.
The probability of rolling a 4 when you throw once a fair die is: P(4) = 1/6.The probability of not rolling a 4 when you throw once a fair die is: P(NO 4) = 5/6.If you roll a fair die four times, the probability of rolling a four on only the secondthrow is:P(NO 4, 4, NO 4, NO 4) = (5/6)(1/6)(5/6)(5/6) = 0.096450617... ≈ 9.6%
The probability is 4/36 = 1/9
It is 1/6.
It is 0.375 = 3/8
