Question

a bag contains 4 red 6 blue and 7 yellow balls one ball is selected at random what is the probability of getting yellow balls?​

Answer 1

Answer: Number of red balls = 4

Total number of balls = 4 + 6 + 7 = 17

Therefore probability of a red ball

= 4/17.

b) Number of the blue and yellow

= 6 + 7

= 13

Therefore probability of a blue or a yellow ball

= 13/17.

c) Total number of balls that are not blue

= Red balls + Yellow balls

= 4 + 7 = 11

Therefore probability of not a blue ball = 11/17.

Step-by-step explanation:

Answer 2

AnswEr :

We have,

• 4 red Balls
• 6 Blue Balls
• 7 yellow Balls

Total number of Balls = 4 + 6 + 7

Total number of Balls = 17 Balls

Formula of probability,

$\star\; \boxed{\sf{\purple{P_{(E)} = \dfrac{Number \ of \ possible \ outcomes}{Total \ number \ of \ outcomes}}}}$

Now,

Probability of getting yellow balls,

Total Number of yellow balls = 7

$:\implies\bf \dfrac{7}{17}$

$\therefore$ Hence, probability of getting yellow balls is 7/17.
