One reason is that genetic differences make us more or less sensitive to the chemical molecules in different foods. Our genes can therefore influence how sensitive we are to bitterness or sweetness among the other tastes. Sounds also influence of taste perception. If your mom LOVED pretzels then you would like them too because it comes from generation but this can sometimes not be true. My mom loves oysters and I absolutely dislike them

graduation ceremony, names were read at a rate of 5 names every two minutes. How many names were read in 3 hours?

emmasim [6.3K]

450

2min= 5 names
1hr= 60 min

2+2+2+2+2= 10 min
5+5+5+5+5= 25 names

10 times 6 = 60 min
25 times 6= 150 names

So 150 names per hour
150 times 3 = 430 names in 3 hrs

Suppose R and Q are two events such that P(R)= .14, P(Q) = .52, and P(R∩Q)= .20, find P(RUQ), are the events mutually exclusive

saw5 [17]

Answer:

P(R I Q) = P(RnQ) / P(Q) = 0.1 Therefore P(RnQ) = 0.1 X 0.35 = 0.035 (The intersection in the centre of a Venn Diagram)

P(RnQ') = 0.15 In a Venn Diagram this is R but excluding the centre intersection with Q. Therefore P(R) = P(RnQ') + P(RnQ) = 0.15 + 0.035 = 0.185

P(RUQ) = 0.15 + 0.035 + 0.315 = 0.5 so 0.5 must be outside the Venn Diagram circles.

Explanation:

hope this helps
