Answer: Probability that at least two of the triplets will win a medal is19/24
Step-by-step explanation:
Total number of cmpetitors=9
Total number of selecting 3 winners out of 9 competitors=9C3=84
Number of ways of selecting 2 out of 3 triplets=3C2
Number of selecting 1 out of 6 others =6C1
Number of selecting 2 out of 3 triplet and o1 out of 6 others= 3C2 ×6C1=18
Number of selecting 3 out of 3 triplets=3C3=1
Total ways of selecting less than 2 or 2 triplets= 18+1=19
Probability that at least 2 of the triplets will win is 19/84
Answer:
123.948 km²
Step-by-step explanation:
We can use the equation: <em>AΔ = 1/2*ab*sinθ</em>, where a and b are the lengths of the sides next to the known angle, and θ is the angle itself.
Plugging in the numbers we know, we get: <em>AΔ = 1/2*22*24*sin(28°)</em>
Simplify: <em>AΔ = 264*.4695</em> (0.4695 is approximately sin(28°))
Simplify: 123.948 km²
