An unfair coin is flipped. if a head turns up, you win $1. if a tail turns up, you lose $1. the probability of a head is . 63 and the probability of a tail is . 37. let x be the random variable for the amount won on a single play of this game. what is the expected value of the game?

The random variable has the following probability mass function:

The expected value of is then

arithmetic sequence

step-by-step explanation:

given that a sequence has terms as

19, 15, 11,

this is represented on a graph

the pattern indicates that the sequence is an arithmetic sequence with i term

a=19 and common difference d =-4

any general term

thus the sequence is reduced by 4 for each successive term starting from 1 and nth term is

24-5n.

first negative term would start after 5th term

5th term =24-25< 0

from 5th term onwards the sequence would be negative.
