A church rings its bells every 15 minutes, the school rings its bells every 20 minutes and the day care center rings its bells e

Dima020 [189]

Answer:

5 : 00 PM

Step-by-step explanation:

Given,

Church ring bells every 15 minutes,

School rings its bells every 20 minutes,

And, day care center rings its bells every 25 minutes,

Thus, the number of minutes after which they will ring together = LCM (15, 20, 25)

∵ 15 = 3 × 5,

20 = 2 × 2 × 5,

25 = 5 × 5,

Thus, LCM (15, 20, 25) = 300

Now, 1 minute = 1/60 hours ⇒ 300 minutes = 5 hours,

Hence, after 5 hours they will ring together,

If they rang at 12:00 PM,

Then they will ring after 5 hours that is 5:00 PM.

If you toss 3 coins 10,000 times, how many times would you expect that exactly 2 heads appear? 3 10,000 3,750 2,500

Simora [160]

The table below shows the outcome of tossing 3 coins

The probability of getting two heads is 3/8

If the three coins tossed 10000 times, the probability of exactly two heads appear is = (3/8) × 10000 = 3750 times
