Answer:
this is only worth 40 points not 80
Step-by-step explanation:
make me a brainliest and i will answer maybe
Let's attribute a to equal probability of 2 and b to equal probability of 3
A=54/360 B=62/360
"or" means you combine the probabilities which means that AvB =116/360
now simply divide 116 by 360 and you get your answer which is 0.32
A is the correct answer my dude
