The probability that an event will occur is 0.1. what is the probability that the event will not occur

0.9

Step-by-step explanation:

For any event A , the probability of event A will occur be P(A).

Then , the probability of not occuring the event A will be given by :-

The given statement : The probability that an event will occur is 0.1.

That is ,

Now, the probability that the event will NOT occur is given by :-

Hence, the probability that the event will NOT occur = 0.9

chemists are often responsible for designing a chemical reaction and analyzing the products obtained from it. one significant part of designing a chemical reaction is determining the amount of each reactant that is needed and the amount of each product that will be produced. in order to do so, chemists use stoichiometry, the quantitative relationships between reactants and products.
