Construct the appropriate probability distribution. (Round your answers to 2 decimal places.) x P(X = x) 0 1 2 b. What is the probability that he makes no more than one of the shots? (Round your answer to 2 decimal places.) P( no more than one shot) = P(X=0)+P(X=1) = 0.36+0.14 = 0.50 Probability c. What is the probability that he makes at least one of the shots? (Round your answer to 2 decimal places.) P( atleast one ) = 1 – P( no shot) = 1 – P(X=0) = 1 – 0.36 = 0.64

Bipolar DAC(digital-to-analog converter) In electronics‚ a digital-to-analog converter (DAC or D-to-A) is a device that converts a digital (usually binary) code to an analog signal (current‚ voltage‚ or electric charge). An analog-to-digital converter (ADC) performs the reverse operation. Signals are easily stored and transmitted in digital form‚ but a DAC is needed for the signal to be recognized by human senses or other non-digital systems. A common use of digital-to-analog converters is generation

INTRODUCTION This is a useful circuit for various purposes. In this circuit a counter is activated when a continuously supplied light is been blocked. It uses a counter IC CD 4033.An LDR enhances the counting process. This circuit an be used for various applications such as to count products going over a belt‚ and for counting persons passed at a point etc The project is done as a prototype and its Real one can display a three to ten digit numbers and can count unto thousands.

Measures of Astronomical Distances • Let’s view the Universe in terms of kilometres – The size of the observable universe is roughly 130‚000‚000‚000‚000‚000‚000‚000 km ! - Obviously measuring astronomical distances in km is inconvenient. - We need much BIGGER units of distance: • Some commonly used distance units: 1 ly (light year) = Distance traveled by light in 1 year = 9.46 trillion km 1 AU (astronomical unit) = average distance between the Sun & Earth = 150 million km A unit of distance‚

symbols (e.g. &‚ *‚ $) Computers do not use these alphanumeric symbols to store information. Computers use binary to store all information...remember? In Converting Decimal Numbers Into Binary‚ you saw how binary was converted into numbers. Just like that conversion process‚ there are agreed-upon conventions for how to convert from binary -> alphanumeric and from alphanumeric -> binary. What are these conventions? all alphanumeric characters are is all the letters and numbers on a keyboard
