Total no. of possible outcomes = 100 + 200 + 50 = 350 {100 red, 200 yellow & 50 blue}

**(i) E ⟶ event of getting blue card.**

No. of favourable outcomes = 50 {50 blue cards}

P(E) = 50/350 = 1/7

**(ii) E ⟶ event of getting yellow card**

No. of favourable outcomes = 200 {200 yellow}

P(E) = 200/350 = 4/7

Bar E⟶ event of not getting yellow card

P(Bar E)=1−P(E)

= 1−4/7 = 3/7

**(iii) E ⟶ getting neither yellow nor a blue card**

No. of favourable outcomes = 350 – 200 – 50 = 100 {removing 200 yellow & 50 blue cards}

P(E) = 100/350 = 2/7
