Here are six number cards.

Mathematics
1 answer:
Helen [10]3 years ago
6 0

Answer:

See explanation

Step-by-step explanation:

The first pair is (-4 and 8)

Because if we add those two values, i. e., 8 + (-4), we will get 4.

Again, the second pair is (-2 and 6). In that case, if we also add those two values, that is, 6 + (-2), we will get 4.

Finally, the third pair is (-1 and 5). Again, we will add the two values. 5 + (-1) = 4.

In each case, we can see that the addition of each pair is 4.Therefore, the total is similar in each pair after arranging the cards.

sleet_krkn [62]

Answer:

The probability that they each win six games is 0.225.      

Step-by-step explanation:

Given : A computer chess game and a human chess champion are evenly matched. They play twelve games.

To find : The probability that they each win six games?

Solution :

Applying binomial distribution,

Here n=12 and p=0.5

P(X=k)=\frac{n!}{k!(n-k)!}\times p^k\times (1-p)^{n-k}

The probability that they each win six games is k=6.

P(X=6)=\frac{12!}{6!(12-6)!}\times 0.5^6\times (1-0.5)^{12-6}

P(X=6)=\frac{12\times 11\times 10\times 9\times 8\times 7\times 6!}{6\times 5\times 4\times 3\times 2\times 6!}\times 0.015625\times 0.015625

P(X=6)=11\times 2\times 3\times 2\times 7\times 0.015625\times 0.015625

P(X=6)=0.225

Therefore, The probability that they each win six games is 0.225.
