You roll a 6-sided die. The probability of getting prime is 50%.
<u>Solution:</u>
Given, that we have rolled a 6 – sided die.
We have to find the P(prime) as percentage.
Now, It means that we have to find the probability of getting a prime number on the face.
On rolling a six sided die, the total possible outcomes are 1, 2, 3, 4, 5, 6
Number of possible outcomes = 6
We have to get a prime number on rolling a die
The prime numbers in possible outcomes are 2, 3, 5
So number of favorable outcomes = 3
Hence, probability of getting prime is 50%.
Answer:
–2.7, –9, –30, –100, ...
–1, 2.5, –6.25, 15.625, ...
8, 0.8, 0.08, 0.008, ...
Explanation:
A geometric sequence is a sequence with the ratio between two consecutive terms constant. This ratio is called the common ratio.
now check all the sequence one by one.
For sequence –2.7, –9, –30, –100, ...
r =
=
=
We see that, all the ratios are same.
So this is geometric sequence.
For sequence –1, 2.5, –6.25, 15.625, ...
r =
This is also geometric sequence.
For sequence 9.1, 9.2, 9.3, 9.4, ...
In this sequence, common ratio is not same.
So, it is not a geometric sequence.
For sequence 8, 0.8, 0.08, 0.008, ...
Common ratio is same so, it is geometric sequence.
For sequence 4, –4, –12, –20, ...
Common ratio is not same. So, it is not geometric sequence .
