Pi symbol raised to the 3 times x raised to the 4
Answer:
Caleb keeps 65% of his mask collection on the wall.
Answer: a) 50%, b) 25%.
Step-by-step explanation:
Since we have given that
Probability of all adults regularly consume coffee P(C) = 65%
Probability of all adults regularly consume soda P(S) = 60%
Probability of all adults regularly either one of them P(C ∪S) = 75%
According to question, we get that
(a) What is the probability that a randomly selected adult regularly consumes both coffee and soda?
![P(C\cup S)=P(C)+P(S)-P(C\cap S)\\\\0.75=0.65+0.60-P(C\cap S)\\\\0.75=1.25-P(C\cap S)\\\\P(C\cap S)=1.25-0.75=0.5=50\%](https://tex.z-dn.net/?f=P%28C%5Ccup%20S%29%3DP%28C%29%2BP%28S%29-P%28C%5Ccap%20S%29%5C%5C%5C%5C0.75%3D0.65%2B0.60-P%28C%5Ccap%20S%29%5C%5C%5C%5C0.75%3D1.25-P%28C%5Ccap%20S%29%5C%5C%5C%5CP%28C%5Ccap%20S%29%3D1.25-0.75%3D0.5%3D50%5C%25)
(b) What is the probability that a randomly selected adult doesn't regularly consume at least one of these two products?
P(C∪S)'=1-P(C∪S)
![P(C\cup S)'=1-0.75=0.25=25\%](https://tex.z-dn.net/?f=P%28C%5Ccup%20S%29%27%3D1-0.75%3D0.25%3D25%5C%25)
Hence, a) 50%, b) 25%.
