A quantity a varies directly as a quantity b, if, when b changes, a changes in the same ratio. What happens to the quantity a if

drek231 [11]

This means that if b doubles, then a will become half as large. For the inverse of the ratio 2 to 1 ("doubles") is the ratio 1 to 2 ("half"). The terms are exchanged; the inverse of the ratio a : b is the ratio b : a. When a varies inversely as b, we say that a is inversely proportional to b.

An experiment involves selecting a numbered chip, some black and some white, from a bag of chips. The probability of selecting a

sp2606 [1]

Answer:

The probability of selecting an odd number given that the chip is black is 0.454.

Step-by-step explanation:

First of all, the value of probability is always less than 1, so the following value of probabilities need to be corrected and are:

Probability of selecting a black chip with an odd number(A)=0.415

Probability of selecting a black chip(B)= 0.915

Probability of A given B is denoted by=P(A | B)

P(A|B) =P(A∩B)/P(B)

P(B)=0.915

P(A∩B)=0.415

P(A|B)= $\frac{0.415}{0.915}$

P(A|B)=0.454

The probability of selecting an odd number given that the chip is black is 0.454.
