A jar contains 77 white, 99 blue, and 1616 red marbles. If one marble is drawn at random from the jar, find the
1. the marble is white or blue.
Answer:
2. the marble is white or red.
Answer:
3. the marble is blue or red.
Answer:
(1)
Obtain the probability that the marble drawn is white or blue.
The probability that the marble drawn is white or blue is obtained below as follows :
From the information, given that
Let S denote the total outcomes. That is, N(S)=32(=7W+9B+16R)
Let W denote the event that the selected marble is white. That is, N(W)=7
Let B denote the event that the selected marble is Blue. That is, N(B)=9
The required probability is,
The probability that the marble drawn is white or blue is 0.5000.
