Answer:
a) 0.15
b) 0.45
c) 0.16
Explanation:
a)
The total probability will add up to 1, so the probability of getting a rat = 1 - 0.35 - 0.4 - 0.1 = 0.15
b)
Probability of cat: 0.35
Probability of hamster: 0.1
Probability of cat or hamster: 0.35+0.1 = 0.45
c)
The probability for getting card out of deck 1: 0.4
The probability for getting card out of deck 1: 0.4
Probability of both: 0.4*0.4 = 0.16
