Answer:
Probabilty of not poor= 0.75
Step-by-step explanation:
total of 11332 bonds.
7311 are good risk.
1182 are medium risk.
Poor risk
= total risk-(good risk+ medium risk)
= 11332-(7311+1182)
= 11332-8493
= 2839.
Poor risk = 2839
Probabilty that the ball choosen at random is not poor= 1 - probability that the ball is poor
Probability of poor = 2839/11332
Probabilty of poor= 0.2505
Probabilty that the ball choosen at random is not poor= 1- 0.2505
= 0.7495
To two decimal place= 0.75
Answer:
![\frac{9}{20}](https://tex.z-dn.net/?f=%5Cfrac%7B9%7D%7B20%7D)
Step-by-step explanation:
experimental probability is the probability of an event occuring when we perform an experiment.
It goes according to the results of the experiment, not the theory behind it.
<u>Probability of landing tails up, therefore, is the number of times it came tails up divided by the total number of times the coin was flipped.</u>
<u />
Hence
P (tails) = 36/80 = 9/20
I think the answer might be 45
I think the answer is 4x - 15 = 6 + 1/2x
