2/10 (or 1/5 ) Times 2/10 (or 1/5).
This will equal a 1 out of 25 chance.
You take the number of items you are looking for ( for example, 2 Tomato Cans) Divided by the total items you have (All 10 cans that are a possibility). Then you take your probabilities, and multiply them.

Answer:
The probability that the average final exam grade of this sample is between 77 and 82
P(77≤ x⁻≤ 82 = 0.8315 or 83%
Step-by-step explanation:
<u><em>Step(i):</em></u>-
Given random sample size 'n' = 40
Mean of the normal distribution = 81
Standard deviation of normal distribution = 6.6
Let x₁⁻ = 77
Z₁ = -3.83
Let x₂⁻ = 77
Z₂ = 0.958
<em>The probability that the average final exam grade of this sample is between 77 and 82</em>
P(77≤ x≤ 82) = P( -3.83 ≤x≤0.958)
= A( 0.958) + A(3.83)
= 0.3315 + 0.4995
= 0.8315
<em>The probability that the average final exam grade of this sample is between 77 and 82 = 0.8315 or 83%</em>
