Answer: The probability of getting all the questions correct is 1/625 Which is 0.002

Explanation: probability is the possible chance of an event to occur. If Richard has a question the has five options

The probability of Richard to get 1 question correct is

1/5 = 0.2

since 1 option is correct among 5 options given.

Because the answer to each question is independent from the outer question, if he answers the 4 question that means the probability of getting the four question correct will be;

1/5 × 1/5 × 1/5 × 1/5 = 1/625 = 0.0016

To three decimal

0.002

Ira Lisetskai [31]

Answer:

Racism.

Explanation:

The fight against racism in American society is still prevalent. History witnessed the struggle of the African Americans who have received the legislative reforms from time to time to enhance their greater participation but continued to fight an equal status to their white counterparts.

Kazeer [188]

Answer:      Grit

Explanation:   What sociologist Paul Tough felt it needed to develop in children was the courage and strength of character to work steadily and persistently toward the set goals, which is grit. Grit is therefore a positive trait that needs to be developed and that implies a strong motivation to achieve goals, so it is not a cognitive trait,  this is about stimulating curiosity, pinpointing and setting goals, and working hard to reach those goals. This trait should be developed in children at school from the earliest days, encouraging and directing children by evaluating their curiosity, directing them to social intelligence that is important when it comes to grit, for example, teaching children to be grateful for their accomplishment and help. There is an emphasis on work that, in combination with social interaction, constant improvement and shifting of criteria, means reaching the goal as well as setting new ones.
