How do I solve question 13 and 14?

xxMikexx [17]

Answer:

13. 13 or 17 (not sure about this, sorry)

14. 28

Step-by-step explanation:

13.

$a_{n} = \{a_{0}, a_{1}, a_{2}, a_{3}, a_{4}, ... \} \\$

if counting the sequence from $a_{0}$ then $a_{4}$ is 17, but if

$a_{n} = \{a_{1}, a_{2}, a_{3}, a_{4}, a_{5}, ... \} \\$

counting from $a_{1}$ , then $a_{4}$ is 13.

14.

$a_{10} = 1 + 3(10 - 1) = 1 + 3*9 = 28$

Georgia [21]

Answer:

65.3%

Step-by-step explanation:

Binomial distribution PMF below (along with a description)

the probabilty of getting 2, 3, or 4 successes in 5 trials is just

p(2)+p(3)+p(4)

p(2)= 5C2*.4²*(1-.4)³ = .3456

p(3)= 5C3*.4³*(1-.4)²= .2304

p(4)= 5C4*.4⁴*(1-.4)=.0768

.3456+.2304+.0768= .6528
