Given:
In a fruit shop 20 percentage of mangoes are rotten.
The number rotten mangoes is 35.
To find:
The total number of mangoes.
Solution:
Let x be the number of total mangoes.
It is given that 20% of mangoes are rotten. So, the number of rotten mangoes is 20% of x.
The number rotten mangoes is 35. So,
Therefore, the number of total mangoes is 175.
Answer:
Step-by-step explanation:
It is convenient to put the numbers into a table and fill in the remaining values. In the attachment, the given numbers are blue. The black numbers are the values that make the totals add up.
__
1. The probability of interest is the sum of the numbers in the table spaces shaded blue. You can find that sum several ways. The usual way used for an "OR" probability is ...
p(<16 or night) = p(<16) + p(night) - p(<16 & night)
= 37.1% + 27.5% - 3.8%
= 60.8%
__
2. This probability is the complement of the one in the first part. It is the value in the yellow-shaded box.
p(≥16 & day) = 1 - p(<16 or night) = 1 -60.8% = 39.2%
