Idon't know how to do ! a game spinner has four colors equally spaced: red, green, blue, and yellow. what is the probability that a single, six-sided die will land on a prime number followed by a spin of yellow or blue? a) 1/4 b) 1/9 c) 1/12 d) 1/36

Remark

You have to work on the die first. You have 3 primes for sure -- 2, 3 and 5. You might wonder about 1. Most experts agree that 1 is not prime. The reason is that a prime requires exactly 2 different divisors -- one and itself. The word different eliminates 1. So the die will give a prime 3 out of 6 chances.

There are 4 colors on the spinner. Two of the four (yellow or blue) will give the correct results. So the chances of yellow or blue coming up are 2 out of 4 chances.

Result

The result of the die landing face up showing a prime is P(prime)=3/6 = 1/2

The result of getting the correct color = 2/4 = 1/2

The Probability of getting both = 1/2 * 1/2 = 1/4

A

area of part 1:

a1=base*height/2=(8+2)*(8-2-2-1)/2=10*3/2=15 ft^2

area of part 2:

a2=length*width=(8+2)*1=10 ft2

area of part 3:

a3=length*width=8*2=16 ft2

total shaded area : a1+a2+a3=41 ft2

total area of the reactangle : a=16*8=128 ft2

total area of the nonshaded region : 128-41=87 ft2
