Answer:
Odds are 3 to 7
Step-by-step explanation:
The odds are defined as the probability that the event will occur divided by the probability that the event will not occur.
Let's find:
Probability of blue marble = 3/10 [ 3 blue and 10 in total]
Probabilty of NOT blue marble = 7/10 [7 marbles are red and green (not blue) and 10 in total]
Hence,
Odds of drawing a blue marble =
The odds are 3 to 7
Answer:
1. 40.00 sq units
2. 37.5 sq units
Step-by-step explanation:
1. Given slant height as 3 and the square base side as 4,
-The surface area of a right squared pyramid is calculated by summing the areas of the 4 triangles and the square base:
Hence, the area of the square pyramid is 40.00 sq units
2. The surface area of a cube is equivalent to 6 times the side of one face.
-Given the dimension of the sides as 2.5, surface area is obtained as:
Hence, the surface area of the cube is 37.5 sq units
