Question

a game has 8 triangles of which 6 are blue and rest are green, 12 rectangles of which 3 are green and rest are blue, and 10 rhombuses of which 3 are blue and rest are green. one piece is lost at random.find the probability that it is a

Answer 1

$dear \: friend \: here \: is \: your \: \\ answer \: ok \: thanks \: for \: asking \:$

here is your solution ☺☺☺☺☺☺

we know that...
..........................

we know Probability P ( E ) = Total number of desired events n ( E )Total number of events n ( S )

Here Total number of events ( Total games ) n ( S ) = 8 + 10 = 18

i ) One piece is lost at random. Find the probability that it is a triangle .

So,

Total number of triangles = 8 , So n ( E ) = 8

And
Probability = 818 = 49 ( Ans )

ii ) One piece is lost at random. Find the probability that it is a square .

So,

Total number of squares = 10 , So n ( E ) = 10

And
Probability = 1018 = 59 ( Ans )

iii ) One piece is lost at random. Find the probability that it is a square of blue of colour .

So,

Total number of square of blue of colour = 6 , So n ( E ) = 6

And
Probability = 618 = 13 ( Ans )

iv ) One piece is lost at random. Find the probability that it is a triangle of red colour .

So,

Total number of triangle of red colour = 5 , So n ( E ) = 5

so answer will be here 5 OK.................... ⛲⛲

note: any doubt ask me..
