class. Of the students taking some other science class, 55% have a B in the class. If a student were selected at
random from the student body of this school, what is the probability that the student is a biology student with a B in
the class?

Respuesta :

The probability that the student is a biology student with a B in

the class is 0.105.

What is probability?

Probability calculates how likely it is for an event to occur. 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 a student scores B on a test is between 0 and 1. If the student scores a B, a value of 1 is given. If she does not, the value of 0 is given.

What is the probability that the student is a biology student with a B in the class?

P (biology class) = 0.3P( b in the class)

= 0.3 x 0.35 = 0.105
