3. Consider randomly selecting a student at PLM and let A denote the event thatthe selected individual has a GCash app on his/her phone and B be the eventfor a Maya app user. If P (A) = 0.5, P (B) = 0.4 and P (AB) = 0.25a. Compute the probability that the selected student has at least 1 of thedigital wallet app on his/her phone.b. What is the probability that the selected student neither use the digitalwallet app?

Given P(A)=0.5, P(B)=0.40, P(Aand B)=0.25

Answered: 3. Consider randomly selecting a…

According to Mendel’s theory, if tall and colorful plants are crossed with short and colorless plants, the corresponding probabilities are 9/16, 3/16, 3/16, and 1/16 for tall and colorful, tall and colorless, short and colorful, and short and colorless, respectively. If 8 plants are selected, find the probability that 1 will be tall and colorful, 3 will be tall and colorless, 3 will be short and colorful, and 1 will be short and colorless.(4 decimal digits)
