Answer:
<h3>The probability that atleast 2 of them come up heads is 0.5</h3><h3>∴ P(A)=0.5</h3>Step-by-step explanation:
Given that three fair coins are flipped.
<h3>To find the probability that at least 2 of them come up heads:</h3>Sample space for the given event is
Let A be the events of getting atleast 2 Heads and is given by
A = {HHH, HHT, HTH, THH}
<h3>∴ n(A)=4</h3>Probability of Getting atleast 2 Heads in 3 Coin Tosses is
The series converges to 1/(1-9x) for -1/9<x<1/9
Given the series is ∑
We have to find the values of x for which the series converges.
We know,
∑ converges to (a) / (1-r) if r < 1
Otherwise the series will diverge.
Here, ∑ is a geometric series with |r| = | 9x |
And it converges for |9x| < 1
Hence, the given series gets converge for -1/9<x<1/9
And geometric series converges to a/(1-r)
Here, a = 1 and r = 9x
Therefore, a/(1-r) = 1/(1-9x)
Hence, the given series converges to 1/1-9x for -1/9<x<1/9

Answer:
The coordinates of are
and
.
Step-by-step explanation:
Let be and
endpoints of segment AB and
a point located 7/10 the way from A to B. Vectorially, we get this formula:
By Linear Algebra we get the location of :
If we know that and
, then:
The coordinates of are
and
