50 ! an experiment involves selecting a numbered chip, some black and some white, from a bag of chips. the probability of selecting a black chip with an even number is 12 . the probability of selecting a black chip is 35 . what is the probability of selecting a chip with an even number given that the chip is black?

Step-by-step explanation:

 The probability of selecting a chip with an even number given that the chip is black = 5/6

Step-by-step explanation:

Let B represents the event of getting black chip,

While E represents the event of getting even chip.

So, according to the question,

It is given, The probability of selecting a black chip with an even number is,

And,  The probability of selecting a black chip is,

Thus, the probability of selecting a chip with an even number given that the chip is black,

( By the conditional property )

⇒

do i do it on a graph?

step-by-step explanation:

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.
