Abi, Ben and Carl each drop a number of identical drawing pins, and count how many land with the pin upwards.
The table shows some of their results.

Two pins are dropped.
Estimate the probability that both pins land 'pin up.
Input note:give your answer as a decimal

yes yes yes yes yes yes yes yes yes

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2

sinn is the total amount of students now and m were the students before, you subtract them both (n-m) and divide that by m. then, since to get a percentage from a fraction you have to multiply by 100, your answer should look like this: n-m/m*100
