Step-by-step explanation:
The probability of success = 8/(8 + 17) = 8/25 = 0.32.
Let X be the random variable denoting the number of successes (number of times the individual won a prize) in four picks.
Hence, X ~ Bin(4, 0.32).
Thus, P(X = 1) = 
We know that
In a period of 4 hours (3 hours of work and 1 hour to refuel)
each street sweepers clean------> 3 miles*3 =9 miles
divide 18 hours by 4
18/4=4.5
4.5 is equal to 4 periods of 4 hours plus 2 hours
Multiply 4 by 9 miles
4*9=36 miles
in the period of 2 hours (<span>in this period there is no refuel)
</span>3*2=6 miles
each street sweepers clean in 18 hours-----> (36+6)-----> 42 miles
two street sweepers clean in 18 hours=2*42------> 84 miles
the answer is
84 miles
Answer:
3/4
Step-by-step explanation:
18:24=18/24
18/24 reduces to 3/4
One person recieves 1. Second person receives 2. Third person receives 3. The amount of cards left over is 94. So the fourth person receives the highest amount possible with everyone in positive numbers of cards.
