[...] According to the formula of conditional probabilities we have . Part B a. One considers the purchase as a draw with a discount. At each draw, a person can therefore buy the product with a probability , or not to buy the product with a probability . There are 30 people, so draws are made. The variable so it follows a binomial law with parameters and . b. According to the binomial formula, we have . For , on a donc . [...]
[...] corresponds to a positive increasing, then decreasing function. The derivative of this function will therefore be positive first, then negative. is therefore the curve corresponding to this derivative. corresponds to a positive and increasing function. The derivative of this function is a positive function. The curve corresponds to this derivative. It follows that represents , represents and represents . 2. The slope of the tangent at the point of abscissa 4 corresponds therefore to the value of the derivative at the point of abscissa 4. [...]
