Suppose each of 12 players rolls a pair of dice 3 times. Find the probability that at least 4 of the players will roll doubles a
polet [3.4K]

Answer:

Our answer is 0.8172

Step-by-step explanation:

P(doubles on a single roll of pair of dice) =(6/36) =1/6

therefore P(in 3 rolls of pair of dice at least one doubles)=1-P(none of roll shows a double)

=1-(1-1/6)3 =91/216

for 12 players this follows binomial distribution with parameter n=12 and p=91/216

probability that at least 4 of the players will get “doubles” at least once =P(X>=4)

=1-(P(X<=3)

=1-((₁₂ C0)×(91/216)⁰(125/216)¹²+(₁₂ C1)×(91/216)¹(125/216)¹¹+(₁₂ C2)×(91/216)²(125/216)¹⁰+(₁₂ C3)×(91/216)³(125/216)⁹)

=1-0.1828

=0.8172

The sum of 6 consecutive integers is 393 what is the third number in the sequence
alex41 [277]
The answer is 

<span>x+1</span>, <span>x+2</span>, <span>x+3</span>, <span>x+4</span> and <span>x+5</span>.

The sum of these six integers is 393 so we can write:

<span>x+x+1+x+2+x+3+x+4+x+5=393</span>

<span>6x+1+2+3+4+5=393</span>

<span>6x+15=393</span>

<span>6x+15−15=393−15</span>

<span>6x+0=378</span>

<span><span><span>6x</span>6</span>=<span>3786</span></span>

<span>x=63</span>

Because the first integer is 63 then the third would be <span>x+2</span> or <span>63+2=<span>65</span></span>

<span><span>
</span></span>

<span><span>Hope its helps :)</span></span>
