There are 10 sweets in a bag.
Valentin [98]

Answer:

See Explanation Below

Step-by-step explanation:

Given

Total Sweets = 10

Red = 4

Green = 2

Yellow = 3

Purple = 1

Required

a & b

The question is not properly presented; however the solution is as follows;

A.

Let P(Yellow) represent the probability of selecting a yellow sweet and n(Yellow) represent the number of Yellow sweets;

P(Yellow) = \frac{n(Yellow)}{Total}

P(Yellow) = \frac{4}{10}

P(Yellow) = 0.4

So, whichever letter that shows 0.4 or \frac{4}{10} is the probability of choosing a yellow sweet

B.

Let P(Orange) represent the probability of selecting an orange sweet and n(Orange) represent the number of orange sweets;

Since, there's no orange sweet in the bag;

n(Orange) = 0

P(Orange) = \frac{n(Orange)}{Total}

P(Orange) = \frac{0}{10}

P(Orange) = 0

In probability; opposite probabilities add up to 1;

Let P(Not\ Orange) represent the probability of choosing a sweet that is not orange

P(Not\ Orange)  + P(Orange) = 1

Substitute P(Orange) = 0

P(Not\ Orange)  + 0 = 1

P(Not\ Orange) = 1

So, whichever letter that shows 0 is the probability of choosing a sweet that is not orange
