Answer:
1:7
Step-by-step explanation:
R = RED | B = BLUE | P = PINK | BL = BLACK | c = chips
10R + 10B + 12P = 32 chips
40c - 32c = 8 black chips
8BL - 3BL = 5 black chips
10R - 2R = 8 red chips
2R + 3BL = 5 chips
40c - 5c = 35 chips
5BL : 35c = 1:7
The probability that next one Susan removes is black chips is 1/7.
What is probability?
The probability is defined as the possibility of an event is equal to the ratio of the number of outcomes and the total number of outcomes.
Total no. of chips = 40
No. of red chips = 10
No. of blue chips = 10
No. of pink chips = 12
No. of black chips = 8
If Susan were to remove 3 black and 2 red chips
So, No. of available black chips = 8 -3 = 5
No. of available red chips = 10 - 2 = 8
Total removed chips = 5
Total no. available of chips = 35
The probability that next one Susan removes is black chips = 5/35 = 1/7
Hence, the probability that next one Susan removes is black chips is 1/7.
