Answer:
a) 34.3%
b) 49%
Step-by-step explanation:
In order to find the probability of a sequence of events, we need to multiply each individual probability by the others in decimal form. Therefore, we need to turn these probabilities into decimal form by dividing them by 100 like so..
70% / 100 = 0.70
Now we multiply all of them together and multiply the product by 100 to get the percentage.
0.70 * 0.70 * 0.70 = 0.343
0.343 * 100 = 34.3%
34.3% is the probability of it raining on all three days. Now to find the probability of it raining on two consecutive days we do the same but multiply only 2 probabilities
0.70 * 0.70 = 0.49
0.49 * 100 = 49%
Answer:
2/3.
Step-by-step explanation:
Ok, so at first, the probability of the teacher picking a girl is 7/9. And then when she takes one girl, it is less, so the probability is 6/8. Then if she picks 2 more girls, then the probability of that would be 4/6, or 2/3.
The slope would be 0 and it is a straight line line
37.50 -25.00= 12.50 so Luisa makes 12.50 more a month than Maria. Divide 100/12.5 = 8. It will take Maria 8 months to be exactly $100 ahead of Luisa.
1. 3/5
2. 15
3. 1/15
4. 1 2/3
