Answer:
0.21
Step-by-step explanation:
Probability calculates the likelihood of an event occurring. The likelihood of the event occurring lies between 0 and 1. It is zero if the event does not occur and 1 if the event occurs.
For example, the probability that it would rain on Friday is between o and 1. If it rains, a value of one is attached to the event. If it doesn't a value of zero is attached to the event.
Probability that a kid who goes to the doctor has a fever and a sore throat = probability a child would have fever x probability a child would have a sore throat
0.7 x 0.3 = 0.21
