Use the Probability Formula.
B
When calculating probability, we are comparing the number of favorable outcomes to the number of possible outcomes. To calculate the probability that a randomly chosen nut is a cashew we will use the Probability Formula.
P=Favorable Outcomes/Possible Outcomes
Substitute values
a/b=.a /30./.b /30.
The probability of choosing a cashew from the jar is equal to 27 or about 0.29. This result corresponds to choice B.
