What is the common ratio in each geometric sequence

4. Correct

5.  Correct

6. times 2

Step-by-step explanation:

4.  3, 6, 12, 24,

6 - 3 = 3

12 - 6 = 6

24 - 12 = 12

2n (n been previous term)

5. 1, 3, 9, 27,

3 - 1 = 2

9 - 3 = 6

27 - 9 = 18

3n (n been previous term)

6. 1/4, 1/2, 1, 2,

1/4 * 2 = 1/2

1/2 * 2 = 1

1 * 2 = 2

2n (n been previous term)

//Hope it helps.

step-by-step explanation:

conditional probability is defined as:

p(a|b) = p(a∩b) / p(b)

in other words, the probability that a occurs, given that b has occurred = the probability that both a and b occur / the probability that b occurs.

in this example:

p(turns 64 | turns 44) = p(turns 64 & turns 44) / p(turns 44).

if someone turns 64, they must have already turned 44, so:

p(turns 64 | turns 44) = p(turns 64) / p(turns 44)

on page 42, we see that of the original 100,000, 94944 turn 44, and 81234 turn 64.   therefore:

p(turns 64 | turns 44) = 81234 / 94944

p(turns 64 | turns 44) = 0.85560
