suppose the probability of someone having a reaction to a medication is 0.025 what is the probability of two out of tree people having a reaction?

Given :

The probability of someone having a reaction to a medication is 0.025 .

To Find :

The probability of two out of tree people having a reaction.

Solution :

Let, P is the probability of two out of tree people having a reaction.

So, P = ( first had reaction ) × ( second had reaction ) × ( third do not had reaction )

P = 0.025 × 0.025 × ( 1 - 0.025 )

P = 0.00061

Hence, this is the required solution.

b. an equilateral triangle inscribed in a circle

step-by-step explanation:

we are given the figure of two circles having a triangle inside.

now, we know that,

"when a figure is lying inside an another figure, then the outside figure is known as circumscribed figure and the figure lying inside is referred to as the inscribed figure".

as we see that, the circles are containing the triangle completely.

thus, the circles are the circumscribed figures and the triangle is the inscribed figure.

hence, we get, 'an equilateral triangle is inscribed in a circle'.
