Answer:
<h2>The answer is 0.23(approx).</h2>
Step-by-step explanation:
The given die is a three sided die, hence, there are only three possibilities of getting the outcomes.
We need to find the probability of getting exactly 3s as the result.
From the sequence of 6 independent rolls, 2 rolls can be chosen in
ways.
The probability of getting two 3 as outcome is
.
In the rest of the 4 sequences, will not be any 3 as outcome.
Probability of not getting a outcome rather than 3 is
.
Hence, the required probability is
≅0.2966 or, 0.23.
Area means times so wouldn’t it just be 6 times 8 which is 48?!
Answer:
(b) Radius of the sphere = 5 units.
Step-by-step explanation:
Here, given:
The volume of the sphere =
cubic units ... (1)
Also, radius of the sphere = x units
Now, VOLUME OF SPHERE = 
So, volume of a sphere with radius x = 
But volume of sphere is given by (1).

Hence, radius of the sphere = 5 units.
We inspect each of the choices and determine which among them is the best answer by multiplying the given time frames to the speed given.
(a) (3 2/5 miles/day) x (4 days) = 13.6 miles (wrong)
(b) (3 2/5 miles/day) x (7 days) = 23 4/5 miles (correct)
(c) (3 2/5 miles/day) x (10 days) = 34 miles (correct)
(D) (3 2/5 miles/day) x (31 days) = 105.4 miles (wrong)
Thus, the answers are B and C.
