Answer:

Option A. 1/8

Step-by-step explanation:

Hello!

The probability of landing on A is 1/4, as 1 outcome out of 4 possible outcomes is A.

The probability of landing on 1 is 3/6, as 3 outcomes out of 6 possible outcomes is 1.

Sice we are asked to find the intersection of the probbabilty of landing on A and 1, we multiply both probabilties.

1/4 * 3/6
1/2 * 1/2
1/8

The correct option is Option A.

Calculate s26 for the arithmetic sequence in which a14=4.1 and the common difference is d=1.7

sweet-ann [11.9K]

Answer:

The value of $s_{26}=84.5$

Step-by-step explanation:

We have given $a_{14}=4.1$

d=1.7

We have to find $s_{26}$

So, $a_{14}=a+13d$ from the formula

$a_n=a+(n-1)d$

When n=14

$a_{14}=a+(14-1)(1.7)=a+13(1.7)$

$4.1=a+22.1$

$-18=a$

$a=-18$

Using the formula:

$s_n=\frac{n}{2}[2a+(n-1)d$

When n=26

$s_{26}=\frac{26}{2}[2(-18)+(26-1)(1.7)]$

On simplification we get:

$s_{26}=84.5$

Flip a fair coin 25 times. what is the size of the sample space? that is, how many different sequences of heads and tails are po

jeyben [28]

There are 50% chance's that it would land on heads or tails. there could be many different outcomes like (H) for heads and (T) for tails many times like this H, T, H, T, H, T.
