We know, s = n/2 [a + l ]
Here, n = 1010
a = 1
l = 1010

Substitute their values, 
s = 1010/2 [1 + 1010]
s = 505 [ 1011]
s = 510555

In short, Your Answer would be 5,10,555

Hope this helps!

Find the probability for the given situations, and then match the situations with the number of times each event is predicted to
Ulleksa [173]

Answer:

(a)3

(b)4

(c)6

(d)5

Step-by-step explanation:

(a)Josie rolls a six-sided die 18 times.

P(she rolls a two)=1/6

Therefore, the estimated number of times she rolls a two in 18 trials

=1/6 X 18

=3

(b)Slips of paper are numbered 1 through 10.

P(the number 10 appear)=1/10

If one slip is drawn and replaced 40 times, expected number of 10

=1/10 X 40

=4

(c)A spinner consists of 10 equal- sized spaces: 2 red, 3 black, and 5 white.

P(red)=2/10

If the spinner is spun 30 times, expected number of red space

=2/10 X 30

=6

(d)A card is picked from a standard deck

P(drawing an ace)=4/52

If the card is picked 65 times and replaced each time.

Expected Number of Aces =4/52 X 65 =5
