Answer:
0.0011904
Step-by-step explanation:
Given that:
Number of slips = 7
Sample space = (1, 2, 3, 3, 5, 6, 7)
Numbwe of slips drawn = 4
Probability = required outcome / Total possible outcomes
Note ; selection is without replacement ;
P(drawing 1) = 1 /7
P(drawing 2) = 1 /6
P(drawing 3) = 1/5
P(drawing 4) = 1/4
1/7 * 1/6 * 1/5 * 1/4 = 0.0011904

27.8 per mile.
417 divided by 15 equals 27.8 miles per gallon
miles/ gallon
/ = per
so
417/ 15
27.8 gallons
x = a³b + b²/ab + 1
x = a² + b²/ab + 1
x = a² × (ab + 1) + b²/ab + 1
x = a³b + a² + b²/ab + 1
