(a) Show why the probability cannot be
10

Answer :

Answer:

Step-by-step explanation:

Red = n

Yellow = 8

Total = n+8

P(Red sweets) = n/n+8

7/10=n/n+8

10n=7n+56

10n-7n=56

3n=56

n=56/3=18.66666

Sweets cannot be a decimal number. It should be a whole number so it cannot be 7/10

Number of sweets cannot be a decimal number. We can conclude that P(Red) ≠ 7/10.

What is Probability?

Probability is simply how likely something is to happen. Whenever we're unsure about the outcome of an event, we can talk about the probabilities of certain outcomes—how likely they are.

Here, let number of Red sweets = n

then Yellow = 8

Total number of sweets = n+8

P(Red sweets) = n/n+8

7/10=n/n+8

10n=7n+56

10n-7n=56

3n=56

n=56/3

n = 18.66666

Thus, Number of sweets cannot be a decimal number. We can conclude that P(Red) ≠ 7/10.
