Seema went to a shop to purchase a child's game along with parent. She elected a child's game which has 9 circles of which 3 are blue and rest are red and 10 squares of which 5 are blue and rest are red. while checking the game, one piece is lost in random.
a) Find the probabiltiy of lost piece if it is a circle of red colour?
b) Find the probabilty is the lost piece is square?
you are correct.
a) 6/19
b) 10/19
@oobleck am I right or wrong???
Thank you so much
To solve this problem, we need to use the concepts of probability. Probability is a measure of the likelihood of a specific event occurring. It is calculated by dividing the number of favorable outcomes by the total number of possible outcomes.
In this case, we have a total of 9 circles and 10 squares in the game.
a) To find the probability of the lost piece being a red circle, we need to determine the number of red circles and the total number of pieces.
The number of red circles is 9 - 3 = 6. (Total number of circles minus the number of blue circles)
The total number of pieces is 9 circles + 10 squares = 19.
Therefore, the probability of the lost piece being a red circle is 6/19.
b) To find the probability of the lost piece being a square, we need to determine the number of squares and the total number of pieces.
The number of squares is 10 - 5 = 5. (Total number of squares minus the number of blue squares)
The total number of pieces is 9 circles + 10 squares = 19.
Therefore, the probability of the lost piece being a square is 5/19.
So, the final answers are:
a) The probability of the lost piece being a red circle is 6/19.
b) The probability of the lost piece being a square is 5/19.
