Answer:
1/12
Step-by-step explanation:
Probability is a ratio derived as the number of possible outcomes divided by the total outcome.
On a number cube, the even sides are 2, 4 and 6. This means that the possible outcome for rolling an even is 3 while the total outcome is 6. Hence the probability of rolling an even P(E)
= 3/6
The probability of rolling a 4 P(4)
= 1/6 (4 appears on one side)
Hence the probability of rolling an even on the first roll and a four on the second roll
P(En4) = 3/6 * 1/6
= 3/36
= 1/12
Answer:
P=0.833
Step-by-step explanation:
The die is six sided so (1,2,3,4,5,6)
Even numbers (2,4,6) P(even)=3/6
Less than 5 (1,2,3,4) P(<5)=4/6
A ∩ B= (2,4) P(A ∩ B)=2/6
The formula to calculate the “or” probability of two events A and B is this: P(even)+P(<5)-P(A ∩ B)
3/6+4/6-2/6=5/6
Answer:
D
Step-by-step explanation:
Since the order does not matter, then it is a combination question,
So you just use the combination technique,
10C3 = 10!/(10!(10-3)!) = 120 ways
Answer:
Hi,
Step-by-step explanation:
Using the pythagorean theorem , let's calculate the apothem of a side:
a²=26²-10²=57=24²
Area of a side: 24*10*2/2=240 (ft²)
Lateral area=240*4=960(ft²)
Area of the base: 20²=400 (ft²)
Total area=1360(ft²)
