Three coins are tossed. What is the probability that two land on heads?

<span>Before you begin, you need to assume some things about the coins for this problem to be solvable.  These assumptions are natural, but they are ESSENTIAL as well, so you shouldn't make them without realizing it.

#1) You have to assume the outcomes on each coin flip are independent.  (Our understanding of the physics of coin flipping easily justifies this assumption.)  the answer is 1/2

#2) You must assume something about the probability of heads on each of the three coins.  The usual assumption is that there is a 50% chance of heads on each toss of each coin.

If each point in the diagram can act as an endpoint, how many distinct line segments can be formed using the set of points
sdas [7]

Answer:

Option D 6 is the answer.

Step-by-step explanation:

the given points are A, D, C and B. If each point in the diagram can act as end points, we have to calculate number of distinct line segments formed.

This ca be calculated in two ways.

(1) We will form the line segments

AB, AC, AD, BC, BD, DC

Therefore 6 segments can be formed.

(2) By combination method

Number of segments = ^{4}C_{2}

= \frac{4!}{2!2!}=\frac{4\times 3\times 2\times 1}{(2\times 1)\times (2\times 1)}

= \frac{4\times 3}{2\times 3}=\frac{12}{2}

= 6

Option D 6 is the answer.

a memory is a memory from a real event that was encoded, stored, but not retrieved for a long period of time; it is retrieved af
Inga [223]

Implicit or Doubtful memory of actual events that was stored encrypted, but was not retrieved for a long time until subsequent events suddenly brought it back to consciousness. The establishing, stabilizing like processes include in this memory.

Implicit Memory is a type of long-term memory and it is also known as unconscious memory or automatic memory. Implicit memory draws on past experiences to remember things without thinking. The power of tacit memory is made possible by past experiences, regardless of how long ago those experiences were.

Second stage of long-term memory formation.

Implicit memory, a subset of procedural memory, allows you to perform many everyday physical activities, such as walking and cycling, without having to think about it. Most of the implicit storage is procedural in nature.

For example:

  • typing on a keyboard
  • brushing your teeth. Riding a bicycle
  • Most people find it easy to ride a bike, even after years of not riding.

pochemuha

Answer:

x= -18

Step-by-step explanation:

We want to isolate x ( move everything to the other side of the equation)

-7 = -1 + x/3

-6 = x/3

x= 3*-6

x= -18
