Answer 1

Step-by-step explanation:

1.the total probability=100%.

probability of getting a cold is 35%.

let the probability of not getting a cold=x

35+x=100

x=100-35

x=65%

2.sample space=(1,1),(1,2),(1,3),(1,4),(1,5),(1,6),(2,2),(2,3),(2,4),(2,5),(2,6),(3,3),(3,4),(3,5),(3,6),(4,4),(4,5),(4,6),(5,5),(5,6),(6,6)

the numbers that give a total of 3 or 5=

2+1=3,1+4=5,2+3=5

probability=numbers that give a total of 3 or 5/sample space

probability=3/21

probability=1/9
