10. There's a spinner.
The probability of a 1 is 2x
The probability of a 2 is x
The probability of a 3 is 2x
(a) Calculate the value of x.
The probability of a 1 is 2x
The probability of a 2 is x
The probability of a 3 is 2x



Answer :

Answer:

Step-by-step explanation:

The total probability = 1,

so, 2x+2x+x =1

5x =1

x= 0.2

so x =0.2 and 2x = 0.4

The probability of a 1 is 0.4

The probability of a 2 is 0.2

The probability of a 3 is 0.4
