Using a binomial distribution considering there's a 30% chance it will rain on any of the three days:
<span>The probability of it raining on 0 days is (1)(0.7)(0.7)(0.7) = 34.3%. </span>
<span>The probability of it raining on 1 day is (3)(0.3)(0.7)(0.7) = 44.1%. </span>
<span>The probability of it raining on 2 days is (3)(0.3)(0.3)(0.7) = 18.9%. </span>
<span>The probability of it raining on 3 days is (1)(0.3)(0.3)(0.3) = 2.7%. </span>
<span>There's a 65.7% chance that it will rain at least once over the three-day period.</span>
Answer:
I'd swap with one on the table (the left one) but with my luck it would be a sword made of rubber
For this question you can say:
1/2 = 8/16
so now you can add easily:
9/16 + 8/16 = 17/16 and that's the simplest fraction but you can also say:
17/16 = 1.0625 :)))

Answer:
0.05
Step-by-step explanation:
We know that the number of marbles is represented by n. We also know that as the number of marbles increases, the volume of water W(n) decreases, since 0.05n is subtracted.
Since 0.05n is subtracted from 32, then 32 must be the original amount of water used if there are no marbles.
Since the amount of water decreases by 0.05 times the number of marbles, the volume of each marble must be 0.05.
