A school administrator asks each student if they participate in a sport and if they participate in a club. The results are shown
1 answer:
Probabilities are used to represent the possibilities of events.
The probability that a student participates in a club given that he participates in sports is 0.6561
The required probability is represented as; P(Club | Sport)
And it is calculated using:
From the table, we have:
So, the equation becomes
Hence, (d) 06561 is correct.

We are given
△ABC, m∠A=60° m∠C=45°, AB=8
Firstly, we will find all angles and sides
Calculation of angle B:
we know that sum of all angles is 180
m∠A+ m∠B+m∠C=180
we can plug values
60°+ m∠B+45°=180
m∠B=75°
Calculation of BC:
we can use law of sines
now, we can plug values
Calculation of AC:
now, we can plug values
Perimeter:
we can plug values
Area:
we can use formula
now, we can plug values
