You simply have to sum the two fraction together to get the total amount of occupied plot. To do so, multiply both numerator and denominator of each fration by the same number, so that they end up having the same denominator.
You can multiply both numerator and denominator of 1/8 by 3 to get 3/24. Similarly, you can multiply both numerator and denominator of 1/6 by 4 to get 4/24.
Now we can easily sum the two fractions together:
So, if 7 parts out of 24 are occupied, it means that there are parts left for other crops. So, the answer is 17/24.
<u>Answer-</u>
a. Probability that three of the candies are white = 0.29
b. Probability that three are white, 2 are tan, 1 is pink, 1 is yellow, and 2 are green = 0.006
<u>Solution-</u>
There are 19 white candies, out off which we have to choose 3.
The number of ways we can do the same process =
As we have to draw total of 9 candies, after 3 white candies we left with 9-3 = 6, candies. And those 6 candies have to be selected from 52-19 = 33 candies, (as we are drawing candies other than white, so it is subtracted)
And this process can be done in,
So total number of selection = (969)×(1107568) = 1073233392
Drawing 9 candies out of 52 candies,
∴P(3 white candies) =
Total number of ways of selecting 3 whites, 2 are tans, 1 is pink, 1 is yellow, and 2 are greens is,
Total number of selection = 3 whites + 2 are tans + 1 is pink + 1 is yellow + 2 greens = 9 candies out of 52 candies is,
∴ P( 3 whites, 2 are tans, 1 is pink, 1 is yellow, 2 greens) =
