Given that,

S = {x : x € N , 4x + 9 < 50 }

We have to express the above set in Roster Form

Given condition,

4x + 9 < 50

➠ 4x < 50 - 9

➠ 4x < 41

➠ x < 41/4

➠ x < 10.2

'x' is any natural number lesser than 10

The above set in Roster Form would be :

S = {1,2,3,4,5,6,7,8,9,10}

A. In A part there is a sample space is of 8 and there is only one case in which no head is appear means only tails comes in every case (T,T,T) SO, the answer is 1/8 B. For an event exactly one head appear So for this cases are Head appears in first tossed (H,T,T) Head appears in second tossed(T,H,T) Head appears in third tossed(T,T,H) SO, the answer is 3/8 C.For an event atleast two heads Cases are (H,H,T) (T,H,H) (H,T,H) (H,H,H) Atleast means kam se kam So there are four cases 4/8 =1/2 For exclusive probability of common part is zero And exhaustive event probability of union is equal to sample sapce.
