Question

Answer this question please.

Answer 1

Answer:

56

Step-by-step explanation:

The probability both spiners land on red: 0,5*0,6=0,3 (0,5 is A spine lands on red and 0,6 is B spiner lands on red)

The number of both spiners land on red is 84.

So we have:

X——>100%

84——->30%

X=8400/30

X=280

The total number of all spines A and B for onse.

The probability to both spiners land on blue is:

0,5*0,4=0,2 (0,5 is probabiliti to A lands on blue, 0,4 is B lands on blue)

The number of both spiners land on blue is:

280*0,2=56
