The teacher of a class needs to select two volunteers from a class of 12 boys and 10 girls. She randomly selects one student and then randomly selects another one . What is the probability she selects one boy and then one girl “think about this one “ can you select both students at the same time or does selecting one affect the other ? Should the denominator change ? is this independent or dependent?

the answer would be 1 1/72

step-by-step explanation:

you can rewrite the equation by separating the parts and then solving individually:

10-9=1

1/8 - 1/9=

find l c d and then combine:

1 1/72

answer: 7

step-by-step explanation:

34.5 cm

step-by-step explanation:

generally for a circular segment of angle, θ° and radius r

arc length

= (θ/360) x circumference

= (θ/360) x 2πr

in our case, θ = 60°, π=3.142 and r = 33 cm

substitute into above formula

arc length

= (60/360) x 2(3.142)( 33) = 34.5 cm

32
