Box A and Box B each contain blue and green pens only. Raphael pick a pen at random from box A and pulao pick a Pen at random from Box B. the probability that Raphael picks a blue pen is 2/3. the probability that both Raphael and pulao pick a blue pen is 8/15 a) Find the probability that pulao picks a blue pen

a)4/5

B)1/15

Step-by-step explanation:

The probability to Rachel pick blue pan is 2/3, p(a)=2/3

The probability to Poalo pick a blue pen is p(b).

The probability the both bick a pan is:

P(a&b)=8/15

p(a&b)=p(a)*p(b)

8/15=2/3*p(b)

P(b)=(8/15)/(2/3)=3*8/(15*2)=4/5

b) we know the probability od picking blue pan and i. The box are blu and green pans. So the probability to pick green is 1- probability to pick blue, so we have:

the probability to Rachal pick green pan is

P(a)=1-2/3=1/3

The probability to Poal pick green pan is

P(b)=1-4/5=1/5

The probability theh both pic green pan is:

1/3*(1/5)=1/15

a

step-by-step explanation:

when a number is between two straight lines it means the absolute value.

to find absolute value you need to know how many numbers is that number away from 0.

when finding absolute value the number will always come out positive

so absolute value of -3 is 3

absolute value of 3/2 is 3/2

absolute value of -2 is 2

absolute value of 3.5 is 3.5

absolute value of -1 is 1

now put these numbers in order:

a)   |-1|, |3/2|, |-2|, |-3|, |3.5|

the answer for this question is : 360°

step-by-step explanation:

we have been given a triangle   we need to tell which one of these is a triangle below to map onto itself.

360° rotation is the complete rotation which eventually leads to the same figure which is given.

the correct will be, that is 360° that will cause the triangle below to map onto itself.
