Create a probability model for the outcome of performing 2 spins. What is the probability of NOT landing on yellow or red at all

Mamont248 [21]

Using the concept of probability, the probability of not landing on yellow or red at all is 1/4.

Creating a square model of the two spins :

Red(R) ; Blue(B) ; Green(G) ; Yellow(Y)

___ R ___ B ___ G ___ Y

R_ RR __ RB __ RG __ RY

B_ BR __ BB __ BG __ BY

G_ GR __GB __ GG __GY

Y_ YR __ YB __ YG __ YY

Sample space = 4² = 16

Combinations without red and yellow :

{BB, BG, GB, GG}
Number of selections without red or yellow = 4

Recall :

Probability = required outcome / Total possible outcomes

P(without Red or Yellow) = 4/16 = 1/4

Hence, the probability of not landing on yellow or red at all is 1/4.

Jim wants to know how much his family spends on water for showers. Water costs $1.50 for 1,000 gallons. His family averages 4 sh

Setler [38]

Since the family spends ten minutes on average per shower and there is 2.5 gallons spent per minute, 25 gallons are used per shower and with 4 shows per day, 100 gallons are used per day, so in 30 days they use 3,000 gallons of water, since water costs $1.50 per 1000 gallons, showering only costs them $4.50 per month
