W
b)
Which letter shows the probability of choosing a sweet that is not orange?​

Answer 1

Answer: B and D

Step-by-step explanation:

Given

There are 4 red, 2 Green, 3 Yellow, and 1 purple sweet i.e. total of 10 sweets

(a)No of yellow sweet =3

Probability

$P=\dfrac{\text{No of yellow sweets}}{\text{Total no of sweets}}=\frac{3}{10}\\P=0.3$

In number line, A, B, and C represent 0.2,0.3 and 0.4

For yellow it is B

(b)sweet that is not orange is red, green, yellow, and purple

So, probability

$P=\dfrac{\text{sweet that is not orange}}{\text{Total sweets}}=\frac{10}{10}=1$

So, D represents it
