Total of 50 students 20 girls play lacrosse 20 boys play either soccer or lacrosse 20 students play soccer what is the probability that a student plays soccer or is a girl?

The probability that a student plays soccer or is a girl = 0.8

Step-by-step explanation:

Total number students playing soccer or lacrosse = 50 ......(1)

Number of boys playing soccer or lacrosse = 20 ........(2)

Number of students playing soccer = 20  .....(3)

Number of girls who play lacrosse = 20 .....(4)

Number of students who play lacrosse = 50 - 20 = 30 ( From (1) and (3))

So, Number of boys playing lacrosse = 30 - 20 = 10  ( From (2))

Number of boys playing soccer = 20 - 10 = 10 (From (2))

So, Number of girls playing soccer = 20 - 10 = 10 (From (3))

So, Total number of girls playing either soccer or lacrosse = 50 - 20 = 30

Now, we need to calculate P(A or B)

So, P(A or B) = P(A) + P(B) - P(A and B)

Hence, The probability that a student plays soccer or is a girl = 0.8

answer:  

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,
