4, 8, 12, 16, 20, 24, 28, 32, 36, 40 = 10 numbers that are multiple of 4
5, 10, 15, 20, 25, 30, 35, 40 = 8 numbers that are multiple of 5
10 + 8 = 18 total numbers are multiple of 4 or 5
Answer:
Step-by-step explanation:
32 x 0.20 = $6.40
32 - 6.4 = $25.60
25.6 x .0675 ≈ 1.738
25.6 + 1.738 = 27.338 ≈$27.34
P = 0.55 or 55 %
First step: Fred has probability of 0,5 when chossing jar 1 or jar 2
Second step : The probability of chossing one chocolate chp cookie in jar 1 is 3/5 and from the jar 2 is 1/2
Then the probability of Fred to get a chocolate chip cookie is
P ( get a chocolate chip cookie ) =( 0.5 * 3/5) +( 0.5* 1/2)
P = 0.3 + 0.25
