A student is taking two courses, history and math. The probability the student will pass the history course is 0.79, and the probability of passing the math course is 0.68. The probability of passing both is 0.57. What is the probability of passing at least one? (Round to two decimal places as needed).

0.97 = 97%

Step-by-step explanation:

The probability of passing at least one is the sum of:

probability of passing history and not passing math,

probability of passing math and not passing history,

probability of passing both of them.

The first one is 0.79 * (1-0.68) = 0.79 * 0.32 = 0.2528

The second one is 0.68 * (1-0.79) = 0.68 * 0.21 = 0.1428

The third one is 0.57.

So, the probability of passing at least one is:

0.2528 + 0.1428 + 0.57 = 0.9656

rouding to two decimal plates, we have 0.97 = 97%

the formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. if a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.

step-by-step explanation:

the 2000 florida legislature amended section 322.05, florida statutes, changing the requirements to obtain a class e license for a driver under the age of 18 holding a learner's license. the following requirements must be met in order to obtain a regular class e license if a learner's license is issued on or after october 1, 2000:
