Answer» Step-by-step explanation: Whenever it is not explicity mentioned that FRUIT and DISTINT, We take them as IDENTICAL. 0 or more orange can be selected from 4 identical oranges in (4+1)=5 ways. 0 or more apples can be selected from 5 identical apples in (5+1)=6 ways. 0 or more mangoes can be selected from 6 identical mangoes in 7 ways. ∴ Total no. of ways in which all of three types of fruits can be selected (the no. of any type of fruits may also be 0), 5×6×7=210, But in these 20 selection, there is one selection where all fruits are 0, hence we reduce 1 selection. ∴ the required no. =210−1=209 Hope this will help youMARK me as brilliant |
