A coin is tossed 5 times; find the probability of getting at least 1 tail. Would you consider this event likely to happen?
grin007 [14]

Answer: 0.96875

Step-by-step explanation:

Probability of obtaining at least one tail on a toss of coin 5 times ;

P(success) in a coin toss = 1/2 = 0.5

Using the binomial distribution formula :

P(x) = nCx * p^x * (1 - p)^(n-x)

P(at least one tail) = 1 - p(0 tails)

P( 0 tails) = 5C0 * 0.5^0 * 0.5^(5-0)

= 1 * 1 * 0.03125

= 0.03125

P(at leat 1 tail) = 1 - 0.03125

P(atleast 1 tail) = 0.96875

0.2) Sharad bought one quintal of onions for Rs 2000. Later he
dalvyx [7]

Answer: Loss, 200 Rs

Step-by-step explanation:

Given

Sharad bought  a quintal of onion i.e. 1000\ kg for Rs.\ 2000

So, the cost price of onion is

\Rightarrow \dfrac{2000}{100}=20\ \text{Rs per kg}

He sells it at 18\ \text{Rs. per kg}

Here, the Selling price is less than the cost price

So, he incurs a loss of 2\ \text{Rs per kg}

For a quintal it is

\Rightarrow 2\times 100=200\ \text{Rs}

\Rightarrow \text{Loss }\ \%=\dfrac{C.P.-S.P.}{C.P.}\times 100\\\\\Rightarrow \text{Loss }\ \%=\dfrac{20-18}{20}\times 100=10\%
