Question

Every morning, siblings Jack and Jill roll a regular six-sided die to determine who will get to ride in the front seat on the way to school. If the number is even, Jack gets to ride in the front. If the number is odd, Jill gets to ride in the front.

Answer 1

3/6

LCM of 6 and 20= 60

3/6=1/2=10/20=10days

so estimated 10 days
