the probability of a radar station detecting an enemy plane is 62%. if 50 stations are in use what is the probability of exactly 35 stations detecting the enemy plane?

Answers

Answer 1

Answer: this is binomial probability with n=50 and p=0.62.

We want binom(50,0.62,35).

One way to calculate this is to use a calculator with statistical functions.

My TI-83 Plus turned out the result 0.061.

I'd be careful answering this because apparently it's a big deal on social media and some really smart guys were debating it or whatever. But this is what I know.

There are only two dates with unique numbers: May 19 or June 18. If Bernard was given a date of either 18 or 19, he'd know right away. The fact that Albert says Bernard doesn't know means the month he was given wasn't May or June. Bernard has now figured this much out, and if he had been told 14 he wouldn't know the answer as there are still two 14s left (July and August) leaving July 16, August 15 and August 17. Bernard must've been given the number 16, because for Albert to say he knows too would rule out August, which still has two remaining dates. That leaves the answer: July 16.

Write 240 and 1500 as products of their prime factor

Answers

Answer:

$240=2^4* 3* 5$

$1500=2^2* 3* 5^3$

Step-by-step explanation:

To find : Write 240 and 1500 as products of their prime factor ?

Solution :

We factor the number by dividing the least prime numbers,

2 | 240

2 | 120

2 | 60

2 | 30

3 | 15

5 | 5

| 1

So, $240=2* 2* 2* 2* 3* 5$

or $240=2^4* 3* 5$

2 | 1500

2 | 750

3 | 375

5 | 125

5 | 25

5 | 5

| 1

So, $1500=2* 2* 3* 5* 5* 5$

or $1500=2^2* 3* 5^3$

240 = 2 × 120
120 = 2 × 60
60 = 2 × 30
30 = 2 × 15
15 = 3 × 5
The 2, 2, 2, 2, 3 and 5 are all the prime factors of 240. So, 2^4 × 3 × 5

1500 = 3 × 500
500 = 5 × 100
100 = 5 × 20
20= 5 × 4
4 = 2 × 2
The 3, 5, 5, 5, 2 and 2 are all the prime factors of 1500. So, 2² + 3 + 5³
