Calculate probability of P (no blue)
Answer to Problem 25SGR
Probability of finding no blue marble in a bag is
Explanation of Solution
Given:
No. of blue marble=2
No. of red marble=5
No. of green marble=8
Calculations:
Here, we have to calculate probability of finding blue or green marbles in a bag..
Total number of marbles = 2+5+8=15
Here, we need to find none of blue marble in a bag. Thus, we can say that there must be higher possibilities of finding red or green marble in a bag.
Therefore we can calculate probability of finding red or green marble in a bag,
Probability of finding red marble is,
Probability of finding green marble is,
Probability of finding red or green marble is,
Probability of finding red marble is,
Conclusion:
Therefore, we are able to calculate probability of finding no blue marble in a bag.
