Answer:
87
Step-by-step explanation:
Complementary angles add to 90 degrees
Let c be the complement
c + 3 = 90
Subtract 3 from each side
c+3-3 = 90-3
c = 87
<span>length of the side = 1.2 / 4 = 0.3 m
area = 0.3</span>² = 0.09 m²
Answer:
Explanation:
<u>1. Sample space</u>
The total number of gums is 2 + 3 + 4 + 2 + 1 = 12.
The number of different outcomes, i.e. the size of the sample space, for the selection of two gumballs from 12 gums is 12 × 11 = 132 different combinations.
2. Number of combinations for the desired outocome.
There are four possible combinations in which one ball is pink and one is yellow:
- first is yellow and second is one of the pinks
- first is yellow and second is the other pink
- first is one of the pinks and second is yellow
- first is the other pink and second is yellow
<u>3. Probability</u>
<u></u>
By definition:
- Probability = number of favorable outcomes / total number of outcomes
Therefore:
- Probability that Pierre selects a yellow and a pink gumball = 4/132
- Probability that Pierre selects a yellow and a pink gumball = 1/33
