P(A) = 0.33

P(A and B) = 0.25

P(B) = ?

-------------

<u>Probability of two events happening is the product of individual probabilities</u>

inysia [295]

Answer: D. False." Within stratified samples, the number of individuals sampled from each stratum should be proportional to the size of the strata in the population."

The individuals within each stratum should be homogeneous or similar in some way.

Therefore, the given statement "When obtaining a stratified sample, the number of individuals included within each stratum must be equal." is  false because within stratified samples, the number of individuals sampled from each stratum should be proportional to the size of the strata in the population.

Andre45 [30]

Answer:

180 different combinations

Step-by-step explanation:

To find the number of different combinations possible, We first find the number of possibilities for each place, and then multiply all possibilities.

Number of possibilities for president: 5

Number of possibilities for vice-president: 6

Number of possibilities for secretary: 2

Number of possibilities for treasurer: 3

Number of different combinations: 5*6*2*3 = 180

(We can form 180 different groups of 1 president, 1 vice-president, 1 secretary and 1 treasurer)
