Question 119512

How can we find the probability that the spinner will stop in area {{{B}}}?

If we divide area {{{A}}} into two equal parts, the spinner will be divided into four equal areas.

One area has a{{{B}}} in it, and that area makes up {{{1/4}}} of the circle. 

The {{{probability}}} that the spinner will stop in area{{{ B}}} is {{{1/4=.25 }}} …or....{{{25}}}%.
