If u work it out and both sides don't equal, then there is no solution.
Example :
2x + 4 = 2x + 6
2x - 2x = 6 - 4
0 = 2....this is incorrect...therefore, there is no solution

A quadratic equation can have no real solution
aa x^{2} +bx+c=0
If b^{2} -4ac\ \textless \ 0 then the equation has no real solutions
Even simultaneous equations can have no solutions
ax+by=c------1
ax+by=d------2
I these two equations the two expressions equal different things, so the equation has no solutions

A fair coin is tossed three times in a succession the sample space is shown where h represents a head and t represents a tail fi
Rudik [331]

Answer:

The correct answer is \frac{3}{8}

Step-by-step explanation:

A fair coin is tossed three times in a succession the sample space is shown where h represents a head and t represents a tail.

Let the experiment A denote that we get exactly one tail in three successive toss of a coin.

Sample space = { hhh, hht, hth, thh, tth, tht, htt, ttt} = 8

Favorable sample = { hht, hth, thh } = 3

Probability of the A = \frac{Favorable}{Total} = \frac{3}{8} = 0.375.

Thus the probability of getting exactly one tail in three successive toss of a fair coin is given by 0.375
