Step-by-step explanation:
The possible outcomes are 1,2,3,4,5,6
P( a prime number and a multiple of two)
The only prime number that is a multiple of 2 is 2
P( a prime number and a multiple of two) = number of outcomes / total outcomes
P( a prime number and a multiple of two) = 1/6 = .17
P(3 or a prime number)
The prime numbers are 2,3,5 and 3 is included in this list so we have 3 outcomes
P( 3 or a prime number) = number of outcomes / total outcomes
P( 3 or a prime number) =3/6 =1/2= .5
P(3 U Multiple of 2)
Multiples of 2 are 2,4,6 and add 3 to the list so there are 4 outcomes
P( 3 U Multiple of 2) = number of outcomes / total outcomes
P( 3 or a prime number) =4/6 =2/3= .67
P(2 U Even number)
even numbers are 2,4,6 and 2 is on the list so there are 3 outcomes
P( 2 U Even number) = number of outcomes / total outcomes
P( 3 or a prime number) =3/6 =1/2= .5

The experimental probability of rolling a 3 is 30%, which is approximately 13% more than its theoretical probability.
The experimental probability of getting a 3 on a die is 30% which is approximately 13% more than its theoretical probability (17%).
Step-by-step explanation:
Theoretical probability of number 3 on a die:
Total no. of possibilities = 6
Probability of getting a 3 on a die each time it is rolled = 1/6
= 0.16667
= 17%
Experimental probability of number 3 on a die:
Total no. of rounds = 4
Rolls each round = 20
no. of 3s in round 1 = 6
no. of 3s in round 2 = 6
no. of 3s in round 3 = 5
no. of 3s in round 4 = 7
Total rolls = 20*4 = 80
no. of times 3 comes up = 6+6+5+7 = 24
Experimental probability of getting a 3 on a die
each time it is rolled = no. of 3s/total rolls
= 24/80
= 0.3
= 30%
Difference = 30% - 17% = 13%
