During february and march ,jack is spending 7 days in the yukon observing endangered species. historically , the region has snowfall that blocks roads 20 days during these months. can jack expect to be able to get around at least 5 of the days. explain

Yes.

Explanartion:

February has an average of 28.25 days. March has always 31 days.

Combined, the two months have an average of 59.25 days.

The days of snow are 20 days in these two months. The probability of a snow day in February and March is

20/59.25 = 0.33755

Out of 7 days, he can expect

0.33755 * 7 = 2.36

days to be snow days which we can round to 2 snow days.

If out of 7 days, 2 days are snow days, then 7 - 2 = 5,

5 days are not snow days. Therefore, Jack can expect to be able to get around at least 5 of the 7 days.
