Sagot :
The probability that all of them are real is 0.01875 or 1.875%
If the diamonds are replaced after each draw:
The probability of drawing a real diamond is 9/14, found by making the numerator the number of real diamonds and adding the total number of diamonds to find the denominator. 5+9 = 14.
To find the probability of all 9 diamonds drawn being real, multiply 9/14 by itself 9 times. = 387420489/ 20661046784. This creates a probability of 387420489/ 20661046784. This cannot be reduced because there is no common factor. To express as a decimal, divide. 387420489/ 20661046784 = 0.01875. To turn this into a percent, multiply by 100. 0.01875*100 = 1.875
Hence, the probability that all of them are real is 0.01875 or 1.875%
