A box contains 79 red marbles 76 white marbles and 41 blue marbles if a marble is randomly selected from the box what is the probability that it is red or blue

The answer is 3/196

Step-by-step explanation:

ok so there are 3 types of marbles so...

1.) 3/?

2.) you add the marbles up (79 + 76 + 41) = 196

3.) you get... 3/196 of a chance

2. angles qrt and qst both measures 156 degrees.

step-by-step explanation:  

we have been given a diagram of a circle and we are told that measure of arc qvt is 156 degrees.  

we can see from our given diagram that angle qrt and angle qst subtends to arc qvt.

since we know that angles subtended by the same arc at the circumference are always equal.

by angle subtended by same arc theorem, measure of angle qrt and angle qst will be equal to the measure of arc qvt.

therefore, angles qrt and qst both measures 156 degrees and 2nd statement is the correct choice.
