If you roll a die 100 times, you would expect to get a 1 about 17 times, because the probability of getting a 1 is 1 in 6, or 0.1667. However, that is theoretical probability; experimental probability - the actual results of doing this 100 times - might not be 17, but if you did this a large number of times, the experimental results would indeed begin to approach the theoretical results.
You can expect to get a 5 about 15 times out of 90.

He should expect it 100 times.
Possible outcomes of one roll = 6Successful outcomes = 1Probability of success on each roll = 1/6Expectation in 150 rolls = (1/6) x (150) = 25 times
The expected number of times is the probability x number of throws. Since you have a prob of 1/6 for a seven, then (1/6) * 160 = 26.67 times you would have success. We generally would round up the expected number of successes to the whole number 27.

With a fair die, you would expect it 60*(1/6) = 10 times.
If George rolls the die 300 times, how many fives will he roll?
1/6 or 300=4
Type your answer here... 15
1/6 of 300 = 50 times.

He should expect it 100 times.
the probability 6o =1/6 = 60%
