20% of the seventh-grade students have math class in the morning. 16 2/3 % of those students also have science class in the morn
Lena [83]
Let x be the number of seventh grade students.

The 20% of the seventh grade students have math class in the morning means mathematically is 20/100.

The 16 2/23% of those students also have science class in the morning means:

16 2/3 & 20/100 = also have class in the morning
83 1/3 * 20/100 = math in the morning but not in science in the morning

30 students have math in the morning but not science in the morning

83 1/3% * 20/100% * x = 30
250/3 * 20/100x = 30
x = 180

There are 180 seventh graders.

1. consider a lottery with three possible outcomes: $125 will be received with probability 0.25, $100 will be received with prob
tigry1 [53]

The lottery's anticipated worth is $80.

Given that,

The probability of receiving $125 is 0.25; the likelihood of receiving $100 is 0.3; and the likelihood of receiving $50 is 0.45.

A) EV=125*.2+100*.3+50*.5=$80

The lottery's anticipated worth is $80.

The expected value is obtained by multiplying each result by its likelihood.

The expected value of the lottery is then calculated by adding up all of these.

This is what we have: ;;

125(0.2) + 100(0.3) + 50(0.5) (0.5)

= 25 + 30 + 25 = $80

B) This is the formula for variance is shown in figure :

So, we can calculate the variance as follows:

.2*(125-80)^2+.3*(100-80)^2+.5*(50-80)^2=975

C) A risk-neutral person would pay $80 or less to play the lottery.
