Answer:
(a) 0.2824
(b) 0.0002441
Step-by-step explanation:
Assuming that the population is large enough to behave as a binomial distribution (between whites and non-whites), the probability of 12 out of 12 juros being white is:

Where p(w) is the proportion of the population that is white:
(a) for p = 0.90

The probability is 0.2824.
(b) for p = 0.50

The probability is 0.0002441.
r= 9 because 45/5 is 9 and it works the same way for the rest of the problems.
<u>Answer</u>
2,737,152a⁵b⁵
<u>Explanation</u>
(2a - 3b)¹⁰ = (2a)¹⁰ - 10(2a)⁹(3b) + 47(2a)⁸(3b)² - 144(2a)⁷(3b)³ - 212(2a)⁶(3b)⁴ + 352(2a)⁵(3b)⁵
The 6th term in this expression is 352(2a)⁵(3b)⁵
352(2a)⁵(3b)⁵ = 352 × 2⁵a⁵ × 3⁵b⁵
= 352 × 32 ×243 ×a⁵b⁵
= 2,737,152a⁵b⁵
