A sight-seeing boat travels at an average speed of 19 miles per hour in the calm water of a large lake. The same boat is used for sight-seeing in a nearby river. In the river, the boat travels 3.1 miles downstream (with the current) in the same amount of time it takes to travel 1.6 miles upstream (against the current). Find the current of the river.

what do u need to know

step-by-step explanation:

answer:   35 % is the probability of a late departure or an early arrival.

step-by-step explanation:

let l represents the late departure and e represents the early departure.

then, according to the question,

p(l) = 12 %,   p(e) = 27 % and = 4 %

and, we have to find out,

but, we know that,

which is the required equation that will use to find the probability of a late departure or an early departure.

therefore,   the probability of a late departure or an early arrival =   35 %

there would only be 50 odd numbers between 1 and 100 so therefor there would be 50 even so that would only be 50 odd numbers.
