Answer:
Total no. of sweets = 10
P (E) = No. of favourable outcomes/ no. of possible outcomes.
(A) P(sweet taken out is a chew) = no. of chew/ no. of total sweets
= 5/10
= 1/2
(B) P (sweet taken out is a toffee) = no. of toffee/no. of total sweets
= 3/10
(C) P ( sweet taken out is a chocolate) = no.of chocolate/total no. of sweets
= 2/10
= 1/5
