Answer:
4.979044478499338 × 10²⁶
Step-by-step explanation:
Combination can be used to determine the number of ways the mice can be selected for the drugs (A, B) and the control group.
Combination factorial is define by ⁿCr = 
21 group of mice receiving Drug A can be selected in ⁶⁰C₂₁ = 
(60 - 21 = 39 ) mice remained for selection of 21 mice for the second drug
Drug B 21 mice can be chosen with ³⁹C₂₁ = 
( 39 - 21 = 18) remained for control with ¹⁸C₁₈ = 
The number of ways the mice can be chosen for drug A, drug B and the control = ⁶⁰C₂₁ × ³⁹C₂₁ × ¹⁸C₁₈ = × × = 4.979044478499338 × 10²⁶

Answer:
one possible number of bonus is 9.
Step-by-step explanation:
Let, the number of $250 bonus = x and number of $750 bonus = y.
We have that bonuses are given in amounts $250 and $750.
Since, the total bonus is $3000.
So, we get,
250x + 750y = 3000.
As, there is atleast one $250 bonus and atleast one $750 bonus.
Let, the minimum number of bonus of $750 be 1 i.e. y = 1.
Substitute in the equation gives,
250x + 750 × 1 = 3000
i.e. 250x = 3000 - 750
i.e. 250x = 2250
i.e. x = 9
Thus, the maximum number of $250 bonus are 9.
Hence, one possible number of bonus is 9.
