OFFERING 50 POINTS
Galina-37 [17]

Answer:

Option B, The sample space has 12 different outcomes

Step-by-step explanation:

<u>Step 1:  Determine which of the following is true</u>

<em>Option A</em> → Heads and an even number are very likely outcomes → This is false, although both of these can occur they don't occur "very likely"

<em>Option B</em> → The sample space has 12 different outcomes → This is the correct option because we take the 2 sides of a coin and multiply it by the 6 sides on a number cube which would give us 12 different outcomes in the sample space.

<em>Option C</em> → The sample space has 8 different outcomes → This is false because it doesn't follow the rules of finding the sample space.

<em>Option D</em> → Each result is equally likely → This is false because a coin flipped can land on heads or tails which is 50% while a number cube is usually between 1-6 meaning that there is a 16.667% chance of landing on a number.

Answer: Option B, The sample space has 12 different outcomes

Find the 4th term of the expansion of (a - sqrt(2)) ^ 8
charle [14.2K]

Answer:

Applying the binomial theorem

{\displaystyle (x+a)^{n}=\sum _{k=0}^{n}{n \choose k}x^{n-k}a^{k}}

Here we have x = -\sqrt{2}, n = 8,

=> 4th term (k = 3) would be:

{8 \choose 3}x^{8-3}a^{3}} = {8 \choose 3}(-\sqrt{2})^{5}a^{3}} = -224a^{3}\sqrt{2}

Hope this helps!

:)
