A child's game has 8 Triangles of which 3 are blue and rest are red and 10 squares of which 6 are blue and rest are red one piece is lost at random find the probability that it is a triangle ,square ,square of blue colour,
triangle of red colour
Answers
Answer:
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 = 8/18 = 4/9
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 = 10/18 = 5/9 ( 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 = 6/18 = 1/3 ( 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
And
Probability = 5/18 ( Ans )

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
And
Probability = 518
