A student demonstrates probably by using a six sided number key with the numbers 1, 2,3,4,5, and 6 the student rules the number keep 246 times predict how many times a 3 or five will be rolled
To predict how many times a 3 or 5 will be rolled out of 246 rolls, we need to first determine the probability of rolling a 3 or 5 on a six-sided die.
There are two possible outcomes out of six that result in rolling a 3 or 5 (3 and 5), so the probability of rolling a 3 or 5 on one roll is 2/6 or 1/3.
To find out how many times a 3 or 5 is expected to be rolled out of 246 rolls, we can multiply the probability of rolling a 3 or 5 in one roll by the total number of rolls:
(1/3) * 246 = 82
Therefore, we can expect a 3 or 5 to be rolled approximately 82 times out of 246 rolls.
