Detailed explanation-1: -3 An even number and a multiple of 3 is obtained in any of the following outcomes 2, 3, 4, 6. So, favourable number of cases = 4.
Detailed explanation-2: -Multiples of 2 from 1 to 6 are 2, 4 and 6. Multiples of 3 from 1 to 6 are 3 and 6. Total number of favourable outcomes =3+1=4. The probability of getting a multiple of 2 or 3 is 23.
Detailed explanation-3: -1 Expert Answer The probability of a 1 on one roll is 1/6 and the probability of an even number on the second roll is 3/6 = 1/2. Since each roll is an independent event, the probability of a 1 on one roll and an even number on the second roll is 1/6 * 1/2 = 1/12.
Detailed explanation-4: -The probability of getting an even number or a 3 is which is about 67%.
