This is known as grandi's series, the proof is in the explanation
Step-by-step explanation:
grandi's series, is given by = 1-1+1-1+1-1+1-1...
1 - = 1 - (1-1+1-1+1-1+1-1) = 1-1+1-1+1-1+1-1 =
1- =
+
= 1
2 = 1
= 1/2
<h2>P(E) = 
or, 0.6092</h2>
Step-by-step explanation:
Given,
There are 348 identical plastic chips numbered 1 through 348 in a box.
To find, the probability of reaching into the box and randomly drawing a chip number which is smaller than 213 = ?
Total number of possible outcomes = 348
Let E be the event of getting randomly drawing a chip number that is smaller than 213.
Favourable outcomes are:
1, 2, 3, .............., 212
Number of favourable outcomes = 212
∴ Probability =
P(E) =
= or, 0.6092
Thus, P(E) = or, 0.6092
