The probability of multiple events happening is calculated by multiplying the probabilities of each event together. This is the case if each event is independent of the other events.

For a fair coin, the probability of tails is 1/ 2 or 0.5, so the probability of all tails in 10 tosess is (1/2)^10 = 1/1024 = 0.0009765625

Correct answer: D

The probability that it will show all heads or all tails is B. 1/512

<h3>Further explanation</h3>

The probability of an event is defined as the possibility of an event occurring against sample space.

\large { \boxed {P(A) = \frac{\text{Number of Favorable Outcomes to A}}{\text {Total Number of Outcomes}} } }

<h2>Permutation ( Arrangement )</h2>

Permutation is the number of ways to arrange objects.

\large {\boxed {^nP_r = \frac{n!}{(n - r)!} } }

<h2>Combination ( Selection )</h2>

Combination is the number of ways to select objects.

\large {\boxed {^nC_r = \frac{n!}{r! (n - r)!} } }

Let us tackle the problem.

If a coin is flipped 10 times , then its sample space is : 2¹⁰

The probability that it will show all heads P(H) is :

\boxed {P(H) = \frac{1}{2^{10}}}

The probability that it will show all tails P(T) is :

\boxed {P(T) = \frac{1}{2^{10}}}

The probability that it will show all heads or all tails is :

P(H \cup T) = P(H) + P(T)

P(H \cup T) = \frac{1}{2^{10}} + \frac{1}{2^{10}}

P(H \cup T) = \frac{2}{2^{10}}

P(H \cup T) = \frac{1}{2^{9}}

\large {\boxed {P(H \cup T) = \frac{1}{512}} }

A baker made two cakes of the same size. • At the end of the day, there was 23 of a chocolate cake left. • There was 56 of a str
Murrr4er [49]
This is the concept of algebra, To solve the question  we proceed as follows;
Number of chocolate cake left=23 
The number of pieces that was left after the cake was divided into 2 equal pieces will be:
23*2
=46

Number of strawberry cake left = 56
The number of pieces that was left after the cake was divided into 3 equal pieces will be:
56*3
=168

Comparing the two fraction, the flavor that had larger pieces was strawberry cake;
This cake was larger compared to chocolate by:
168-46
=122
The answer is Strawberry by 122 of a cake

Tomtit [17]

Answer:

  • P = 2.5x

Step-by-step explanation:

Let the length is x, then the width is 1/4x.

<u>Find the perimeter of rectangle:</u>

  • P = 2(l + w)
  • P = 2(x + 1/4x) = 2x + 1/2x = 2 1/2x = 2.5x
