Question

A fair spinner has 10 equal sections: 3 red, 4 blue and 3 green.

It is spun twice.

What is the probability of getting 2 different colours?

Answer 1

Answer:

Outcomes with the same colour: 3*3+3*3+4*4=34. Outcomes with different colours: 100–34=66. Their probability:66/100=0.66. The probability of two of same colour is 2*0.09 + 0.16 = 0.18 + 0.16 = 0.34.
