Question

there are four flash cards- one red,one green and two blue.what is the pobablity of drawing a blue card maths class vii​

Answer 1

Step-by-step explanation:

probability of drawing red card=n(R)=1

probability of drawing green card=n(G)=1

probability of drawing blue card=n(B)=2

P(B)=no. of blue cards/total cards

=2/1+1+2

=1/2

Answer 2

Answer:

Total no. of outcomes= 4 (1+1+2)

let A be the event of getting a blue card.

no. of outcomes favorable to A= 2

P(A)= no. of favorable outcomes

         total no. of outcomes

p(A)= 2÷4= 1/2
