Answer:
347 and 865
Step-by-step explanation:
Let the two number be x and y
Therefore, from the given information:
x + y = 1212
x - y = 518
Rewrite both equations to make x the subject:
x = 1212 - y
x = 518 + y
Equate equations and solve for y:
1212 - y = 518 + y
694 = 2y
y = 347
Substitute found value of y into one of the equations and solve for x:
x = 518 + 347
x = 865
Therefore, the two numbers are 347 and 865

<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
