The angles around the point a total 360°
the lines AB and AC make a sector of the circle.
we are told that the circumference of that sector is 2/5 of the total circumference
so 360/5 ×2 =144

x = 144°

the following ratio is true for the given circle

\frac{arc}{circumference} = \frac{x}{360}

that is \frac{2}{5} = \frac{x}{360} ( since AB is 2/5 circumference )

cross-multiply

5x = 720 ( divide both sides by 5 )

x = 144

1. Find the probability of this set of independent events. rolling a six on the first roll of a 1-6 number cube and rolling an o
jeyben [28]
For the first question, the chance of rolling a six is a 1/6 chance because there is one six and six different sides that could be rolled. As a percent, it would be 16.6 %. The probability of rolling an odd number on the second roll would be a 3/6 chance, which as a percent is 50 %. For the second question, both probabilities are 33 % because in both instances you are drawing three cards from nine total, so it would be 3/9. For the third question, the probability of drawing a blue marble is 3/5, because there are three blue marbles and five total marbles. As a percent, this is 60 %. Following this up with a green marble would be 2/4, because there are now 2 green marbles and four total marbles. One of the marbles was not replaced, so we have one less marble. 2/4 as a percent  is 50%.
