Prime number is a whole number that has no possible divisors that 1 and itself. Prime numbers are 2, 3, 5.7.11,13,17,19,23 and 29. From 1 to 10 there are 3 prime numbers: 3,5 and 7.
The probability can be calculated as the ratio between the number of "good" events and the total number of possible events. There are three "good" events (3,5 or 7) and 10 total events, so the probability that the spinner lands on a prime number is: 3/10. So, none of the given options is true.
Based on the choices, I think the 84 in the problem is not really the number 84. Instead, it is 8 raised to the power of 4 or 8⁴
Thus, 8⁴ = 8 x 8 x 8 x 8 = 4,096
8 x 8 = 66
64 x 8 = 512
512 x 8 = 4,096
So, my answer is d. 4,096
