Question

out of 100 in a bag,25 are red, 30 are blue 45 are white. find the probability that a ball draw from the bag is a,red b, blue c,white d,find the some of probabilities got in (a),(b)and(c) please give answer right​

Answer 1

Answer:

Probability=No. of favourable outcome/ total no. of outcome

Step-by-step explanation:

Total balls=100

a) Red= 25/100=1/4

b) Blue=30/100=3/10

c) White=45/100=9/20

Answer 2

Answer:

Let the random experiment be a ball drawn from a bag

Let red balls be r1, r2, r3.....

Let blue balls be b1, b2, b3...

Let white balls be w1, w2, w3...

S{r1, r2, r3, r4,.... r25, b1, b2, b3,.... b30, w1, w2, w3,...... w45}

n(s) : 100

Event A : The ball drawn is red

A { r1, r2, r3,... r25}

n(A) : 25

P(A) : n( A) / n(s)

: 25 / 100

: 1 / 4

Event B : The ball drawn is blue

B{ b1, b2, b3,.... b30}

n(B) : 30

P(B) : n(B) / n (s)

: 30 / 100

: 3 / 10

Event C : The ball drawn is white

C{ w1, w2, w3,... w45}

n(C) : 45

P(C) : n(C) / n(s)

: 45 / 100

: 9 / 20

P is probability

n is no. of
